somebody please tell me why is that? and how do i get more life out of my battery?

Maybe your phone only goes up to 9 hours...

Maybe it's kernel related.. Are you on custom rom already?

My Droid on a JB ROM has the Android OS consume about 90% of the battery and it dies after 8 hours of screen off time, airplane mode. *shrugs* if anyone has a solution id like to know.

This has probably to do with something that is running in the background.
your phone apparently doesnt go into "deep sleep mode" Only in this mode you lose just few % per night.
I recommand to shut off your phone, take out the battery for a few seconds, put it back in, charge it in one go, then turn it on again. See what happens.

You can, of course, sleep with the charger in.

Welcome to Android, for the most part, our battery life sort of sucks :/

[Q] 4.2.1 Battery Drain Issues?

Hi guys, I've flashed the 4.2.1 ROM by albinoman887 and only when the screen is on the lowest brightness it uses a lot of battery, really quickly.
Thread can be found here
When it's on standby the battery lasts for about 7 hours, but when it's on it lasts for around 45 minutes. Please help
I've tried
- Wiping battery stats
- Calibrating battery.

Your horrible cell signal is at least part of the problem. Your phone is constantly pinging the towers looking for a better connection. That's a serious battery hog.
You may have the wrong radio for your carrier. Or you may live in a dead zone for your carrier.
Also, is this your first battery cycle after a full wipe? I get results like that for the first discharge cycle after install. But then it becomes fantastic. Drain the battery all the way until the phone shuts off. Then charge it using a USB cord on your computer (not the standard power charger) for an hour past when it says 'full'. The slower USB charge can help to give it accurate voltage readings while charging so it doesn't stop charging too early. See if that helps.
The battery on Albino's 4.2.1 is pretty spectacular for most people, so the good news is that this is probably a fixable issue on your end.

The signal was when I'm out and about, most of the time I have 3-4 bars on HSDPA, I may do a full 24 hour charge or get a new battery

I have this problem too.But if i flash last build,baterry life is good.

XT1225 shutting down at 20%

Guys, my phone it's shutting Down at 20-25%, I'm using Rr 8.1.0 buts is not that random reboot problem
It's just 20% and shutdown, and when I plug the charger just show the percentage it was when turned off. What this could be?

i'm afraid to buy new battery and the problem is on the motherboard and not on the battery. i had a S4 with the same problem and i change the battery but the problem persist.

Well looks like is a "common" problem with Oreo. Also mine and gives some bad percentage readings. If I charge to 100%, then reboot to recovery, the battery percents changes to 94 - 96%, reboot to system and this numbers persist.
If I let the phone all day and at night I reboot to recovery again, I lose like 20% of battery, example: Android says that my battery is at 60% but in recovery says 40% and when the system start the battery reduce to 40%.
Also have some random "turn off" and then, when I power on I lose around 5 - 10% of battery.
And in resume, the using time of battery life is 1 hour max.
This doesn't happen in Nougat.

Under 2 hours battery life on S7 Edge

I have had this problem for quite some time... however I always thought it was completely normal until... I noticed it is not. I read many reviews about this phone found that I should be getting around 5 to 6 hours which seems amazing but completely out of reach. I switched from an old iPhone 6 which made this seem like much better battery life. I used to get a bit more battery life but now not anymore. I am rooted and have tried many methods but all have failed. I am running a close to stock ROM called 'The Galaxy Project' which I like having. I have wanted to post this for quite some time. I charge my phone overnight and need it for the whole day, however it dies at half of the day. I have:
- Always on display off
- Screen res on 720P
- Bluetooth off when I don't need it
- Easy turn on is off
- Mtweaks is set to be a balanced power consumption
- Greenify is running on many apps
- Battery health is approx 84% which is said to be 'good'.
Sometimes I manage around 2 hours and 30 mins but this hasn't been happening very often recently.
Feel free to ask any questions... I have read many forums and none have seemed to help!! I really want to fix this problem.

Redmi Note 6 Pro battery health under 20% after two months

In mid-January I've bought a Redmi Note 6 Pro Blue 3GB / 32GB. My idea was to use it mostly for music (Spotify and Google Play Music) and video (Netflix and IPTV streaming) as a secondary phone. I was so happy with its battery life and overall performance in the first couple of weeks that I even considered using it as my main phone. However, after less than two months of very irregular use, the phone's battery life dropped quite drastically.
I tried a factory reset yesterday, but the issue remains. AccuBattery estimates the battery health at 19% of the advertised 4000 mAh. Do I have a defective battery? Because this certainly does not look like a software issue - I also tried removing all the apps I could to ensure there is no battery hoarder eating away my battery's juice, including most MIUI software through the adb tools I've seen recommended in a thread here and no luck. It's probably even worse than before. What should I do?
I'm running the latest MIUI Global 10.2 stable 10.2.2.0 (OEKMIXM). No root, bootloader is locked.

^ One and a half hours of battery life after charging it up to 100% post-factory reset. 15min after this screenshot, the battery is at 9%. How is this possible on a phone purchased less than two and a half months ago?
