Tips and tricks to prolong battery life

Switch To Wi-Fi
If you live in a place where Wi-Fi speeds are good or hot-spots are abundant, you should really consider switching to Wi-Fi. This will save you from the great amount of power that a constant 3G connection needs. Hit Menu > Settings > Wireless & Networks > Wi-fi to do the needful or you can use the easy way of dragging down that status bar and switching on from there. Also, you can permanently turn off your 3G by holding the power button and deactivating the data connection (froyo) or going to Settings > Wireless & Network > Mobile Networks > un-tick the data enabled box.
Switch To 2G
While 3G connections are fast, they also drain up a ton of battery. If you cannot switch to Wi-Fi for a particular reason, try switching to 2G when you are not in need of a high-speed connection. Sure, the slow speed can kill, but it’s good enough if you want your email updates and your contact sync. Plus, it can be very useful when you need a data connection but your battery is low. Switch to 2G from Menu > Settings > Wireless & Networks > Mobile Networks > Use Only 2G Networks.
Turn Off Sync
If you aren’t comfortable about turning off mobile data access entirely, you should consider being selective about the apps which are sync with the cloud. The best is to turn off syncing entirely for maximum gains. Also, some apps have an option to increase the timeout at which it pings a server for a sync. Try increasing that to the maximum possible interval. Settings for sync can be controlled from Menu > Settings > Accounts & Sync > Background Data. Also, disable Auto-sync from the same screen.
Control The Screen Brightness
Unless you are in direct sunlight for a long time, consider switching your phone to the lowest possible brightness. This works pretty well indoors and also gives your Android battery life a pretty significant boost. Screen brightness can be controlled from Menu > Settings > Display > Brightness.
Calibrate Your Battery
You have to be rooted for the following procedure. Calibrating the battery is a very simple procedure. First of all, charge your phone until is gets to 100%. Then, keeping the phone in charging, switch it off because it will charge for a little longer. When it vibrates and shows 100% battery, boot into CWM recovery mode by pressing the following buttons: Vol up + Vol down + Home button + Power button. Then go to Advanced and click on wipe battery stats. If you don't have CWM recovery, you can use an app called battery calibration.
If anyone has any more tips, please do not hesitate to contribute.
Note: These tips are from another website. I only modified them for our specific phone and added the battery calibration tip. I don't take any credit for creating them but they did take a while to modify so a don't hesitate to hit the thanks button!​

I just searched this and it lead me to another forum. However, the persons experience was that when he used the task killer, he would use the auto kill every 30 minutes option. He reported that the apps he had killed would just start up again a couple of minutes later so this caused battery drain (This is the thread i read it from). It is also bad for android to use task killers which is written on this website.

missing hint:
delete Gallery3D, use e.g. quickpic instead

Juice defender is a great way to save battery. You can manually set which apps to use internet. It also turn off internet at screen off. The only problem is Airtel users have to deal with annoying usage popup after everytime the internet is disconnected

@Smonic
you should mention SetCpu profiles...governors too
coz we "all" know if we have set governor to performance at 1000mhz....battery goes down faster....

I read in some places on the internet that in some instances Juicedefender would drain battery even more, beacause it switches Wifi on and off frequently.

[HOW TO] Solve battery drain issue of YU Yureka.

If your YU Yureka's battery last upto only few hrs. Try this :
First check Battery status (Settings->Battery)
If you find Mediaserver listed number one battery drainer with more than 50% battery uses, then there is issue with Media storage
Now go to Settings-> Apps ->All, select Media Storage & disable it. Clear data & reboot. Now enable it & reboot.
Check battery uses after some time Mediaserver will not be number 1 & may not be in the list also. Even if it is listed , it will not take much battery.

How to save battery life on your Android device: 20 Tips
Most smartphones have either a Lithium Ion battery or a Lithium Polymer battery. Both are Lithium Ion though, and as such, do not have a ''memory'' which means you don't have to fully charge or discharge them at the beginning, and partial charging is fine throughout their life. In fact, these types of batteries suffer from low voltage, so it's actually much better to charge them, even if only a little, whenever you have the chance rather than to fully charge and fully drain them.
1. Use a dark colored background
2. Make apps darker too
3. Get rid of auto-brightness
Don't use display auto-brightness. It may sound good, but auto-brightness is usually way brighter than you really need. It's much better to manually set a super low brightness level that is still comfortable, and then just bump it up when necessary. This is one of the main ways to improve your battery life as the screen is one of the biggest battery suckers.
4. Vibrate away!
Switch off vibrate. Unless you really need that added awareness, turn off vibration. It actually takes more power to vibrate your phone than it does to ring it. Turn off haptic feedback too. Sure it feels cool, but it doesn't really add anything to your experience, and it's another battery drainer.
5. Don't use a knockoff
Only use original batteries or respected third party manufacturer batteries. Saving a few bucks on a battery that might damage your beloved smartphone is a poor choice indeed, and may also deliver sub-standard battery performance.
6. Having a timeout is good
Set your display's screen timeout to as short a time as is practical for you. Just think, if your screen timeout is set to a minute, it'll use four times the amount of power to have it on, every time you switch your screen on, than if your timeout is set to 15 seconds. Studies report the average smartphone user turns their smartphone on 150 times a day, so anything you can do to limit that frequency (through self-control or other methods listed below) will help keep your battery running for longer.
7. Get your notifications to leave you alone at night
Set ''sleep times'' or ''blocking mode'' to switch off Wi-Fi and mobile data when you don't need them. If your phone is basically off limits at work, set your device to not ring, vibrate or connect to the internet while you're at work. Likewise, you can set your phone to airplane mode when you're asleep or use sleep or blocking modes to set up limits for what your phone does during certain times of the day, whether that's while you're asleep, at work or in a meeting. Get to know the specific settings your ROM offers. Not only will you have to fiddle with your phone less throughout the day (or night), but you'll be saving on battery life too.
8. Your phone doesn't have to be smart all the time
Turn off smart features like air gestures, smart scrolling and the like, Unless you really use these features every day, they're just using battery power for a feature you don't use.
9. Nor do you need to be connected 24/7
Turn off GPS, Bluetooth, NFC, Wi-Fi and mobile data whenever you don't need them. Turning off location data, or setting it to use Wi-Fi or 3G data rather than GPS works perfectly well. Only turn on Bluetooth and NFC as long as you need them, and there's no need to have both Wi-Fi and mobile data turned on at all times. If you use Wi-Fi a lot though, say at home and at work, then it makes sense to keep set your Wi-Fi to ''Always on during sleep'' as this uses less power than to have your Wi-Fi reconnecting every time you wake your phone.
10. Try out Dynamic Notifications
Use lock screen widgets or notifications if your ROM supports them, or install an app that does it for you like Dynamic Notifications. You'll be able to get basically all your content without having to unlock your phone fully and navigating around. You still need to light your screen up, but you'll have it on for much less time than normal. using a lock screen notification app with a black background can save your battery life significantly.
11. Don't get bogged down by widgets
Ditch widgets you don't really need, especially those that are connected to the internet like weather widgets.
12. Don't let your apps fall behind the times
Keep your apps updated. There's a reason developers constantly update apps, and many of these reasons are memory and battery optimizations. Keeping your apps updated also means you have the best optimizations available. Likewise, delete old apps you no longer use, as these may be running background processes that chew up RAM and battery life.
13. Use your battery saving mode, now!
If your phone has a battery or power saving mode or other battery management option, make use of it.
14. Explore the battery saving features on your phone
All ROMs, whether it's stock Android, OEM UI's like TouchWiz or custom ROMs like CyanogenMod, have various settings in the menu to help conserve or optimize battery consumption here and there. Find these various options for your device and ROM and make them work for you!
15. Choose when you sync your data
Turn off auto-syncing for Google accounts. If you don't need every single Google account updated every fifteen minutes, just go into your Settings and Google account and turn off auto-sync for those apps you don't need constantly updated.
16. Be the master of your app updates
Set apps to update only when you launch them. If you rarely (or very frequently) open an app, it might be better to only have it update when you do so, rather than updating automatically all the time via push notifications or sync intervals. If you only check email once a day, why not let the app update then only, and if you're on a widget or app every couple of hours anyway then why not have it update each time rather than every fifteen minutes when you're not even looking at it
17. Be app update savvy in the Google Play Store
Change your Google Play Store settings to manual update your apps. If you have the Play Store set to auto-update, you might have fifteen apps updating when you least expect it, destroying your battery life (and data plan) without you realizing it. If you use even half of these battery saving tips you'll see a marked improvement in your battery life.
18. Turn off Google hotwords
Stop your phone from always listening. Google's "Ok Google" voice searching is a fantastic and often very functional feature. The problem is that it can play havoc with your battery. Go into "Google settings" from your app drawer and tap the "voice" heading. On the next page, select '"Ok Google' detection". In this menu, the best option for battery life would be to untick all boxed, but if you are a fan of "Ok Google", tick only the "From Google Search app" box to ensure your device is only primed while in the Google app.
19. Get rid of animations
Disable animations. This process may differ slightly from device to device but the crux of it should remain the same. Go to your settings and to the "about phone" page. Tap on the "build number" around 7 times. You will be notified that you have become an "Android developer" (don't worry, enabling the Android developer options doesn't have any adverse affects, it just adds another option in your settings menu). Go back to your settings and tap on the newly inserted "developer options" menu at the bottom. On the next page, scroll down to where it says "window animation scale," "transition animation scale" and "animator duration scale", and switch all of these off. Your device's interface may no=longer look as pretty, but the battery life will be better.
20. Make your location services more battery-friendly too!
Turning off location services isn't just a fantastic way to save on your battery, it saves on your data plan too! Go into your settings and you will find "location" under the "personal" heading - tap on it. At the top of the next page it you will see "mode" in this menu you will be able to set the options for how your smartphone determines your location. Select "battery saving" on the following page.

The temporary solution for the YU Yureka heating problem is to switch the mode of phone from performance/balanced to battery saver mode. This reduces the continuous heating of the device
Hit thanx if helped.

Scheduled power on and off option yu yureka- any codes
there is no inbuilt scheduled power on and off option in yu yureka. It is possible to write code from developer options?

Hit thanks if it helps.

I own a Yureka Yu since April 2015. From the beginning there was a problem of heating and phone would randomly reboot. The Battery life was ok after the update Of late the battery drains fast and doesn't charge 100%. Even after keeping for charge overnight the battery shows only 89%.

Location battery drain

Hello,
I have a huge battery drain on my phone because of bad working of location services. I have it "on" with "battery saving but this keep awake the system when the screen is off. If I turn off the location the battery doesn't drain anymore. Why "battery saving" doesn't work properly?

Wouldn't say I've a huge drain on my battery with Location services ('Access to my location' enabled) on battery saving mode, but I have these 2 set to disabled in Settings:
Location services > Menu (≡ at the bottom) > Scan settings > 1. Wi-Fi scanning (disabled), 2. Bluetooth scanning (disabled) - are these enabled/disabled for you?
--------------------------
Also, I often use 'Ultra' battery setting if phone is not in use for more than 10-15 minutes. This saves a lot of battery throughout the day, plus one can still receive & send texts/messages with this enabled.
For quick & easy access to 'Ultra' battery setting, you'll want to edit the drop-down Shortcuts menu to place the 'Ultra battery' shortcut in a better position (please see pic enclosed to view where I've placed it in my drop-down Shortcuts menu).
Exiting this 'Ultra' battery mode is also easily done from the main screen, & it takes only a few seconds to return the phone to full functionality.
To emphasise how good this is, my P8 loses only 1-2% charge overnight with this setting enabled.

Deep sleep makes my oneplus 5 to not receive facebook messages

Hello,
When I spent some hours without touching my oneplus 5, he enters on deep sleep mode.
When he is in that mode, I noticed that he can't get Facebook messages (at least when he is connected to 4G network).
Only when I interact again with him, he starts receiving those messages when they were actually sent to me some hours ago.
Is this a normal behaviour? Is it happening to you as well? Can I do something to adjust this?
Thank you

Please check battery settings. There is an option to restrict background activities if you activate battery saver mode. Its a bit hidden.

I checked. Battery saver mode is actually disabled
EDIT: nevermind. I found what you are saying. But that option I think is always active and it not depends on battery saving mode being active or not. It's under "Battery Optimization" option. Thank you so much

Yes couldn't check it because my phone is in repair. You're welcome, glad I could help

Do you have this one enabled?

How to disable Bluetooth battery optimization?

I just can't seem to get there. I'm on stock, latest, unlocked, not rooted. I can go to battery|battery optimization and turn off battery optimization for apps but Bluetooth isn't listed. I can go to apps, show system apps, see Bluetooth, it shows battery is being optimized, if I click to change it takes me to list of apps like above where I could do it but Bluetooth isn't listed.
It's kind of important, I'm a diabetic and wear a glucose sensor but the phone loses touch with the sensor too often. I have to carry my old phone just for that at the moment...
Thanks!

This workaround may help.

I experience the same with my OnePlus 7. I think I deactivated all battery saving options for xdrip+ and even disabled the "sleep standby activation" in the androids battery > battery optimization > advanced optimization settings. But still one hour after falling asleep my device doesn't get any more readings until I wake the screen. Could you find a solution? Perhaps we have to flash a custom ROM to get rid of some unadjustable system settings?
I will try the workaround from Glaux. Needs another night.
[...] Workaround didn't work.

Advanced battery optimisation
Hi
There is an advanced menu accessed from the battery optimisation page, the one with all the apps.
You need to click the 3dots and select it. It seems directly related to bluetooth and the other radios sleeping.
