Diagnosis of the battery status
1. Using a system of means
iOS system has the means to view the battery information.
Settings ->Major ->Statistics ->Battery use.
An experiment: record the data, and then lock the device, wait 5 minutes, unlock the device again. Again, write down the information. If the waiting time increased to 5 minutes, then everything is fine. If 5 minutes added to the time of use - hence, some background Process prevent device go into sleep mode. Try to find and stop such processes.

In the "Capacity" is displayed the real capacity of the battery at this time.
Attention! If this figure is less than claimed, it is normal! In an average year is lost 200-400 mAh (depending on usage). If you have already lost 600-1000 mAh, should consider replacing the battery

Attention! If this figure is less than claimed, it is normal! In an average year is lost 200-400 mAh (depending on usage). If you have already lost 600-1000 mAh, should consider replacing the battery
3. Diagnosis by computer
Program requirediBackupBot. Install it, run and wait for your device. Click "More Information", as shown in the screenshot:
The window will give detailed information about the battery:
CycleCount - number of discharge / charge cycles complete;
DesignCapacity - battery capacity, declared by the manufacturer;
FullChargeCapacity - the actual maximum available capacity (it is always less than DesignCapacity);
BatteryCurrentCapacity - the current level.
For the analysis to be divided on FullChargeCapacity DesignCapacity and present the result as a percentage. For example, if DesignCapacity 1550 and FullChargeCapacity - 1300 the "battery life" will be 1300/1550 = 83.9%, and "depreciation" - 100-83,9 = 16.1%, which is normal for one to one and a half years operation. In the fall of the resource to 60% should consider replacing the battery.

Which battery consumption figures are considered normal
- Consumption by 10% at night included social networks, the Internet and etc., and is a common standard for such apparatus ..
- Consumption by 40-80% for 5-8 hours at included 3G, gps, youtube and the like, sots.setyah, chats, icq, permanently on-screen running games / movies, as is normal and standard behavior
- Consumption of 100% per day is perfectly normal under the conditions listed above
How to deal with the hardware battery problems
- If you bought the device, and by means of diagnosis described above, realize that you have a serious problem with the battery, you can return the device within 14 days.
In the case of a technically complex product, the consumer, in the event of deficiencies in it, has the right to refuse to execute the contract of sale and to demand the return of the amount paid for such goods or to demand to replace it with a product of the same brand (model, article) or the same product. brand (model, article) with a corresponding recalculation of the purchase price within fifteen days from the date of transfer of such goods to the consumer.
Law on Consumer Protection
- If you do not have time to return the device in time, you have to go to SC.
- If there are minor hardware battery problems with them can be controlled by the methods described below.
What services / programs / services / features most strongly consume battery power
Location services (Constant use of GPS devices). Turning off - Settings ->Privacy (iOS 6-7) / Privacy (iOS 8) ->Location Services.
Updating Facebook content. User comment:
fitness tracking. Function appeared in iOS 8.2. To disable it, go to Settings ->Privacy ->Movement and fitness.
I was able to repeat this behavior on several iPhone with the same result: if you remove the background Facebook functions, the charge indicator of the percentage increase
Turning off - Settings ->Major ->Content Updates.
Upgrading applications and content (iOS 7-8)
You can disable the selective application (Settings ->Major ->Content Updates)
Upgrade applications can also be disabled (Settings ->iTunes Store, App Store ->Automatic update)
Push e-mail :

Turn off Push email (in Settings ->Mail, addresses, calendars ->Loading data).
Push applications.
User comment:
Turn off these notifications, go to Settings ->Notifications ->(Your application) ->On a locked screen.
Auto Brightness . She constantly uses the light sensor.
Disable this feature, go to Settings ->The screen and the brightness.
Updating Facebook content. User comment:
During the test, Facebook is constantly found himself in the list of active processes, although I did not use it. So I tried to turn off Location Services, and Content Updates for Facebook, and you'll never guess what happened: the number of remaining charge interest increased from 12% to 17%. Wow. I've never seen this on the iPhone. As I recall, iPod Touch repeats this behavior, though I have long enough to check it for the last time. On the iPhone indicators of the remaining charge as a percentage of the normal order.

Push e-mail :
Comment from a user:
I've seen a lot of devices that Push is a major cause of battery discharge, but I also saw a lot of devices with the Push, who had excellent battery life. In fact, everything depends on the server configuration and the specific e-mail. Try changing the settings for samples per hour, thirty or fifteen minutes to see if the quick battery drain stops. If this does not help, switch Push back. You can also try to disable Push for individual accounts if you have several of them. Just check with the help of the above described test, whether it's help to solve your problem.
Incredibly often especially with the Exchange e-mail, there is a situation when the phone as if the loops are constantly checking email. When this happens, the device is discharged about six hours and Standby indicators and Use Settings>Main>Statistics will be identical. These values ​​are the same, not because "the firmware is damaged, so that the phone constantly checks for new mail and the phone does not normally go into the sleep state.

User comment:
Notifications default do not cause too rapid discharge of the battery, so do not rush to turn them all. However, each message wakes your device for 5-10 seconds and it can accumulate. If you get 50 alerts per day and do not do anything with them, it adds 4 to 8 minutes for the use of time, which in turn reduces the time that you can use your device.
Turn off those annoying notifications for applications from which you do not want to receive them. The difference may seem small, but over time accumulates.

What not to do if you want to conserve battery power
- Do not need long to keep the device charged, after reaching 100%.
- No need to constantly be fully discharged device.
- No need to constantly turn off the device completely.
- No need to constantly close the application (throw away from multi-tasking). iOS automatically freezes the closed application.
- No need for constant monitoring of the battery charge. From this knowledge to "squeeze" out of the battery you still can not do anything. Therefore, it is better to turn off the display of the charge as a percentage (Settings ->Major ->Statistics ->Charge as a percentage)
Typically, for a long happy life of the device should adhere to two rules:- Normally, you should not consider themselves smarter than programs (and their creators). Yes, mistakes happen, but, as a rule, the program is working as it should, and better "knows" what it needs.
- It does not interfere - not hammer head (variants "works - do not touch" and "do not know - do not go").
- Normally, you should not consider themselves smarter than programs (and their creators). Yes, mistakes happen, but, as a rule, the program is working as it should, and better "knows" what it needs.
What actions to take to increase battery life
- Respect the temperature limits. Avoid using iPhone at a temperature below 0 or above 35 degrees.
- Turn on the auto-lock device. Go to Settings ->Major ->Automatic lock and set a small interval, e.g., 1 minute.
- You can also use specialJailbreak-tweaks, eg,WeeKill Background Pro. The tweak settings, select More Options ->Close Every X Minites and set the desired value, after which the process will close unused.
How doesJailbreakandPrograms from Cydiaon low battery?
HimselfJailbreakIt does not have any influence on the discharge of the battery unit.
However, along with himself the Jailbreak, also set a number of other support programs.
One of them - MobileSubstrate - is an environment for running tweaks. She is always running, and, as a continuous process that can consume battery power. The larger set of tweaks - the more they will "load" the battery, and the faster the discharge apparatus. Therefore it is recommended to install only those tweaks that you really need.
More about MobileSubstrate you can read here:Cydia.

Tweaks, most battery power is
- Springtomize
- Activator
- All tweaks that make "active" Springboard (dynamic change icons, "live" wallpaper and so on.
- All tweaks are continuously using in the wireless network (do not forget that some of the tweaks work even when the screen is off, that is not frozen, as do the other applications of the AppStore).
- All tweaks and programs dynamically updating information on the device (e.g., desktop widgets).
Whether to trust the program to monitor the power consumption?
Why is the battery consumption statistics are sometimes significantly different?
All these tweaks can show anything. Battery capacity they determine indirectly the voltage and discharge current, counting them on a special algorithm or by selecting from a table of standard values. What algorithms and values ​​are used - it is known only to the developer and not the fact that everything is correct.
Batteries to the article, are not charged to 100% capacity and did not discharged to zero. It is harmful, reduces the service life. Please do not confuse the charge up to 100% power capacity and "full" charge, well, with the rank similarly.
Typically, the battery controller has - a microchip with a set of electronics for measuring current and voltage and a control program (or a separately arranged). It is he who controls the flow of energy. When the voltage in the power supply circuit falls below a certain (predetermined) value, the controller gives a signal to the operating system to issue a low battery warning to the user. On the screen you can see anything - zero percent, one, five (as programmed, again). Zero percent charge indicator does not mean that the battery current is ended, a signal to the user. Electrical is constructed with a stock for two reasons:
- foolproof: zero - Come on, goodbye;
- from the overdischarge protection: as I said, it's bad for the battery, plus the residual current circuit supplies power to critical devices (eg, hours). In addition, from the battery powered controller, which is why discharged into the trash iPhones often can not boot, even when connected to the charge: the controller can not turn on the charging process, because he is not receiving power - the battery is no energy. And so it appeared - to include the charging process. Vicious circle.
Concluded: zero the display - it's not a real zero in the battery. Always remains a certain amount of energy.
Now about charging. There are several options for charging (charge current, charge voltage - google if interested), they differ in the speed and the highest attainable level of charge. Typically, the controller charges (oh, I'm tired of this word, but do not have a synonym ...) the battery on a specially written program, and this process is uneven: about 3/4 the battery is charged quickly, and the rest is typed slowly. Upon reaching a predetermined voltage controller stops the supply of energy in the battery: the indicator have 100%. But this is - not the maximum possible charge. Why? Because a further charge requires a lot of time and heats the battery. Those. it is simply ineffective and can damage equipment.
Again conclude that 100% on the display - it is not 100% in battery, and a little less.

It is worth whether to do a battery calibration (full charge / discharge)?
Can we thus increase battery life?
There is no such thing as a "calibration". This 90th batteries were suffering from memory effect, and can be tricky algorithm for making n charge-discharge cycles and receive + 500% capacity.
Modern batteries (we are talking about the Li-ion), and do not need to be calibrated, no special charging technique. Therefore, the meaning of calibration no.
The fact that there devaysakh statistics "since last full charge" - not a dogma, but an attempt to somehow divide the time intervals that the user can figure out that the "full charge is enough for him to XX hours."
Serviceable lithium batteries charged enough to hold more than half, and everything will be fine. That is, if you have a need then charged a half-empty battery during the day (well, for example, I doubt that will have time to get to the next outlet) - safely charge, it will be better than to give the unit to discharge to zero.

Why when you first turn on / activating a new device or after flashing the old battery very quickly sits down, but after a few days everything will stabilize?
We do not think about what is really going on inside the operating system, but from personal experience, many people know that the first few days after flashing / reset / update the device, to put it mildly, "sausage". It's like a car break-in when the parts to adapt to one another, are selected gaps, warm up joints, etc. At that time, caches are created, the database, perform file system indexing, etc. Then it all ends.
Those. the first few days of the smartphone runs on. Then he begins to work for you.

What is the impact on non-original battery chargers?
Be sure to recommend that you use only original chargers!
Apple equipment, unlike others, for some reason especially demanding on the quality of the periphery. The original cable is much more expensive, "Chinese", but as a rule, working a long time and attention to itself no longer requires. This is - a good investment.
Therefore, if your charger is broken and needs to be replaced, the best solution is to buy a powerful 12-watt adapter, designed for the iPad 4: it can be used to chargeall Apple mobile devices . Additionally, you can find this article Knowledge Base.

Apple previously warned their customers to refrain from the use of non-original power adapters, as these may lead to various malfunctions iOS-devices - up to the circuit and fire. But as it turned out the other day, third-party charging can also cause damage to one of the iPhone 5 chips.
As noted iMore publication with reference to one of the British service centers, aftermarket charging and USB-cable incapacitate U2 IC chip that controls directly charging the battery, the sleep button, and some USB functions. Its incorrect operation may give rise to many problems: the charge indicator damage to sudden power devaysa and problems with its further inclusion.

Powerful battery charger from the "big" the iPad universal:

Why night sometimes takes 1-2% charge, and occasionally 5-10%?
It is necessary to take into account such factors as the stability of the network. When powerful cell tower network caught stably, smoothly, so the battery is almost no wear. But if the network is unstable, iPhone is constantly searching for a signal, respectively, and the battery will be consumed faster. I tested repeatedly in different places (and if you go on the train, the battery gets even faster). Therefore, iOS blame for all the wrongs does not make sense. Then Put though iOS7, though iOS8.1.2, though iOS8.1.3 - the result does not change.
