well... I think is "normal" is it got stuck at boot or restarted itself... that "normally" happen when flashing another rom: you have a #% when doing TitBu and those stuff then you flash a rom and when finally bootup you got [usually] -#% and since it was from boot to boot it can't get the correct graph... or at least thats what I think

not normal i think... i've seen thing like this once - with older version of Zeus (don't remember which one exactly). When i had SoD, after i remove battery (warmer than usual) and put it back, the graph was similiar.

its either a self boot or an sod.... ive experienced alot of these myself =P.... the screen goes black then when you press the power button repeatedly goes very bright then it reboots then the battery chart gets cut off like that.....
for my part i think its mostly cos i install and uninstall alot of apps (even those that are not supposed to work for our ob) so im pretty sure its not a rom problem cos i dont see anyone else talking about it....
i posted sometime back on another thread abt my phone always losing 3g and rebooting itself (after what seems like the 3g hangs) but that problem, (although not for its intended purpose) has been solved for me by using the FD off patch that Huexx posted for his rom.
it could also be (im guessing here) due to not clearing old data (ie battery charge levels) after flashing a different rom... i read somewhere that someone has an almost similar problem coming from froyo to custom rom. something about the battery charge remembers the charge and discharge levels from the prev rom and cannot charge/ discharge properly with the new rom causing the erratic power levels.... its something like... in your picture, shows that it rebooted at 90% and went to abt 80% cos in actual fact you have used your battery to 80% just that the system failed to update this in the background hence it forced itself to reboot to get the proper reading again... again for this last part im really guessing....

by the way my phone has not any problem sod fc or restarting etc. everything is normal except battery graph.

Problem with kernel

Can anyone help? I just got my Nexus 6 a few days ago and have already had a lot of problems. Battery draining fast, randomly turning off, phone battery "dying" at 45% etc. I heard the Franco kernel could fix this so I flashed it via fast boot (storage wasn't mounted in recovery so I couldn't do it that way. But in any case the fast boot flash went through and the battery started draining normally so I thought all was good. I even took a screenshot just in case.

That was until my phone randomly turned off and when I turned it back on the battery was draining super fast again so I checked kernel and here is what I believe is the stock kernel reverted back on its own
I don't know what causes this but it's happened twice and not sure how else to proceed.

When I got my N6 about 19 months ago the battery life was not enough for a day.
I got a better battery life as follows.
a. Deleted apps I hardly use.
b. Switch apps to use black/dark themes. Use layers with dark themes.
c. Deleted apps with only a white background.
Replaced f.i. Gmail by Aquamail.
At this moment I use the lite stock rom MOB30m of Danvdh. Prerooted and debloated.
I suggest to start with flashing this ROM.

I signed up for the Android N beta and updated, that seems to have fixed the draining problem but not the battery dying at 50% . Any ideas how to fix that? Or do I need a new battery?

Sounds like a calibration issue. Google that and try and see if that helps.

N920I Sleep of Death

Ever since I rooted and installed custom roms on my device, the phone would sometimes have a black screen and become unresponsive. The only way to use it is to perform a reset by pressing volume down + power button.
When I go to have a look at the battery history, it shows a gap in the time the phone was non responsive, suggesting it was turned off. However, the battery level also is much less and you can see a downward slope in the battery chart. I have attached a screenshot of the battery chart.
Because of this problem, I reflashed stock Rom and also Sky high kernel to solve deep sleep problem. But I still am getting the sleep of death.
I noticed it tends to come after I use the GPS (Google Maps).
Current config:
Stock rom
Sky high kernal
Twrp
Any help is much appreciated.

You can try another kernel.

Sudden Battery Drain - 50% to 4%

Hi guys
S10 5G (SM-G977B) owner. Been using since launch. Exynos version with latest update - G977BXXS2ASJ7.
Always recharge to 80% battery to maintain health for lifespan of phone. Avoid leaving it plugged in overnight.
This looks like a bug that I have noticed following the last major update which introducted a bunch of Galaxy Note features such as Samsund DeX for windows.
Phone will literally hold 4% charge for hours. Picture attached. Is there a fix for this or is this a known issue? Couldn't find anything online with all posts about high drain touching on the usual suspects (always on display, 5G switched on, performance mode, screen brightness etc)

Have you tried a factory reset? Or ever done a clean install using Odin files with CSC_OMC?
I'd suggest factory reset as this seems like a glitch with your device. It's definitely not a known issue with the 5G or any S10 variant.
Hopefully it's not a battery or other hardware issue that's apeared. But the reset will help rule that out. It's a good idea to do it once in a while anyway.
Also, not charging overnight, and only charging to 80%, is saving you next to nothing on long term battery life. Unless you plan to keep the phone for something like 4 or 5 years, you'll see absolutely no difference in the life of the battery over the next years or two by doing that. You're best to charge to 100% and get the full 100% charge during the day.

Thanks mate. No factory reset yet attempted. Always painful re-synching all the apps and 2fa services so generally try to avoid. I have attempted Davlik cache wipe but that made no tangible benefit. Accubattery reporting 85% battery health and this is despite my battery babysitting ways (3774mAh actual vs 4400mAh design)

Question Important battery drain not understood

Hello all,
I recently buy an OPPO find X3 pro and I'm really annoying with battery life. I could not succeed to reach more than 3h of SOT and would like to know if it's normal.
I already perform a factory reset without success (back-up and restore from a PC). I don't know what to do know.
I've installed GSAM and allow "more stats" with ADB and notice that Android System is the most battery consumer but I don't know if it's normal. In idle, power consumption is acceptable 3-5% overnight but as soon as use it I see battery level decrease rapidly.
I've also a Galaxy watch. At the begining I saw a high drain from "watch plugin" but I authorize it to run in background + no battery optimization and it seems Ok now.
Does anyone have a solution to help me solve this problem ? I really like this new phone btw (after my old OP6T) but the battery is really awful...
Thanks in advance !
Below some screenshots :
2h20 of SOT only and 35% left

Hi,
I had the same problem. Did the following:
1) Reset to factory settings;
2) Restarted the phone;
3) went to Settings > Battery > More Settings > Optimise battery use > set all apps to Auto-Optimise.
If you want to test if you probably have a faulty battery you shoud do the following:
1) charge your phone till 100%;
2) restart the phone;
3) disconnect it from the charger;
4) switch on airplane mode;
5) leave the phone unused for 8-10h.
If the battery drops bellow 93%, you have a faulty battery that needs to be replaced.
Bare in mind that this processor is very power hungry, nevertheless OPPO should have predicted it and pack with the phone a, at least, 5000mAh battery.
Hope it helps!
