Two questions:
1. what sort of battery discharge rate would indicate that my tab has a problem? i was reading using aldiko last night for about an hour, and the battery went from about 85% to 70%. it seems like this is higher than it should be for just passively reading an ebook. thoughts? does this battery burn rate seem legit? how do i know when i have a problem? is there a good way to test my battery in terms of whether or not i am getting teh batery life i should?
2. the battery stats in "settings" are not working properly. there is no breakdown of which components are using teh battery. there is nothing under teh graph at all. any one else have this issue? thoughts on how to fix?
Sense the jb update has anyone else notice there batteru percentage changing on its own. For example ill be at 60% and it will go down one or two percent then go back to 60% or even 61% it works across the board in this manner. Hope somebody else is having the same problem and can help me figure this out.
Yes i think there is a bug in jb update. After unplug it says 98% and after 7 minutes it changes to 99%. Lol
Hi everybody
I've got a major battery issue with my three year old Nexus 10.
The battery indicator shows something around 75%, drops to 0 in a split second, switches in energy saving mode (notification and navigation bar are turning red) while it shuts down.
To verify I made an Automate Flow saves the battery charge every second to a text file. Result:
Code:
82,82,82,81,81,81,81,[...],73,73,73,73,0,0,0,0,0 EOF
Okay, it thought to myself, after three years the battery is broken. So I bought a replacement battery (Samsung original) and replaced it - but nothing changed.
To clear all old stats (and running Android 6.0.1) I wiped everything TWRP offered and installed CM13 - but nothing changed.
Now my only guess is, that there's some EPROM (or other memory hardware) that stores battery stats.
Can you, dear forum, help me fixing that issue?
No one?
Has anyone of you guys changed the manta battery, yet?
Same thing after OTA upgrade in D6563
I'm facing the same problem here with my d6563, after the MM OTA update i started to face quick vertical battery drop, but we're not the only ones, some users are reporting this issue in a lot of devices, some of them after update, some others after rooting, some of them just after some apps update, and the thing is that nothing seems to work, some users claim to have solved the issue, but they are just talking to fast, because the problem comes back the same day, they just think taht the battery data is accurate but then the drop accurs, si, i'm starting a new thread listing all the solutions tghat senior members have recomended and failed in order to track this problem to his roots once in for all, it's been happening since kitkat at y has come worse since marshmallow
keep in touch to see what we can figure out about this.
Battery _stats_ issue
I had, ummm, similar issues with my TCL S720 (in less degree) and now with TCL M2U (TCL Meme da 3N M2U AKA Alcatel Flash+) phones.
TCL M2U has 3500mAh battery capacity.
After full charge it discharge normally to ~40%. Behind 40% it is discharged to 1% for a few minutes and shuts off!
If then I charge it again to 100% then it eats about its full capacity (~3500mAh) - checked with Keweisi USB Doctor and shows 100% charge, but discharges to 40% again.
On other firmware there is similar effect but for 30% level or 15% level, it depends on firmware.
I think that the battery is OK but the charge percentage display is wrong.
Another strange thing is when I see the charge level using Ampere app. It shows i.e. 50% battery level and 3.762V voltage on the battery. Then I plug it in charger. For a short time the voltage rises to 3.8V and more but the battery level is lowered to 45%! Also if I charge the phone from discharged state then the battery level is 1% for the long time, then it quickly raise to ~30% and then shows charge process normally (almost linear). The USB Doctor show the charge process smooth almost all time (from stronger current to weaker).
So I join to the 1st post question: where is the battery's _real_ voltage level data?
i know its really silly but i seriously just cannot interpret a battery graph. how do i know till what time my battery lasted from the first charge till the next charge and the screen on time i also got.
as you can see in the images attached, my batter graph are quite ridiculous.
I am normal user, and since the battery's fully charged, I did make some phone call, sms msgs, web surfing time to time, so that was ordinary use as usual, but my battery didn't drain gradually but the indicator falls down 10% at once after stuck at 36% for several hours which is quite abnormal.
could you please tell me what the heck is wrong? because I can't estimate when it's gonna shut down since the indicator sucks
thank you. and sorry for my english. hopefully I delivered the meaning correctly
Is it possible that a relevant third-party app is causing trouble? Perhaps give Safe Mode a try just to test that.
Reboot phone / delete dalvik cache and find a different socket if the above solution doesn't help.
