[Android Q&A, Help & Troubleshooting] its_dows:
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:

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?

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.
[Android Q&A, Help & Troubleshooting] HEKPOMAH:
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%! :eek: 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?

[Sony Xperia M4 Aqua] Pablo_mb:
Hi everyone.

I'm Pablo and recently i bought an M4 Aqua Dual E2363.

First thing that i do after this is run for XDA and search a way to root my phone.

Found some tutorials, but no one of these worked for me.

So i thought "The fact that my cellphone is a dual version means that all the to-do texts about how to root M4 single SIM will not work for me?"

Can any good soul help me to find a tutorial that works for me?

To anyone that already root your own M4 aqua, this help to fix things like overheat and lag in some games?

If this question was already answered, please paste a link to this here.

And sorry for my english. I have not practiced as it should.

Thanks since now :D
[Sony Xperia M4 Aqua] mfpss95134:
Rooting E2363 is very easy,i remember that there is a thread about rooting M4 Aqua. I followed the instructions, and finally got the root access as well as the twrp rec installed on my E2363.
[Sony Xperia M4 Aqua] Pablo_mb:
Please, can you indicate what method describes here in forum did you use?

Cause when i try with flashroot + adb drivers and etc, in the final i always receive a message that says something like

"Your phone can't be rooted"

If you help me, it will means a lot. Cause i want a lot root my phone.

Thanks to answer anyway :D

Didn't work for me.

But when i turn off and on my phone to try to acesso TWRP, and hold power + down volume, nothing happens...

Thanks anyway, dude. I will try change my cellphone for another ....
[Sony Xperia M4 Aqua] GedsoN:
and then friend, get it?
[Sony Xperia M4 Aqua] Pablo_mb:
Nope. I'm still with my E2363.

The good news is, with android 6, the cellphone runs smoother than when he was with android 5.

Even if it's not a rooted one, i can run heavy games and emulators that before i just can't.

So, for now, i'm good with this phone.

If someone knows how to root this phone with new android 6, please tell me.

I want to install an alternative ROM in this phone.

See ya.

[Elephone P9000 Questions & Answers] davidedgreen:
I bought the handset in UK and everything works fine except I cannot get the mobile data to work. I have a good reception, the handset shows 3G but no arrows to the side of it. I have changed the APN settings to my network (Talkmobile), switched on mobile data etc. but still no mobile data, please help.
[Elephone P9000 Questions & Answers] mixterz:
when my phone dropped to 3g the internet didn't work either here in Ireland on 3 mobile.

4g would rarely stick, just putting the phone in my pocket sent it back to 3g.

this is most likely a hardware problem not software.
[Elephone P9000 Questions & Answers] davidedgreen:
Thanks, but I've never got mobile data to work at all, the APN settings are all correct and the 3G symbol appears on the screen, just no arrows next to it.
[Elephone P9000 Questions & Answers] arlrb:
A fair few people are having the same problem, myself included.

It works better if you switch to 3g only, but sometimes that doesn't help either.

Let's all hope elephone get there act together on this, it's all very well having a great screen, CPU etc, but with no network data (& sometimes calls) it counts for nothing.
[Elephone P9000 Questions & Answers] davidedgreen:
Thanks for this. In the APN settings I just changed the APN type from 'net' and 'MMS' to 'default' and this worked.
[Elephone P9000 Questions & Answers] arlrb:
It's weird, is there some sort of learning process with this phone & network settings?

When I first got the phone it was rubbish, but as i used it more & more it got better. But then I rooted it & did a factory reset & same again. This morning I put the darksense rom on & it was still rubbish. But as the day's gone on its got a lot better - 4g & everything is working fine.

But thanks, I'll bear the APN change in mind
[Elephone P9000 Questions & Answers] arlrb:
There are lots of APN settings to edit, I don't want to mess with what I don't know, although sometimes that's the only way. Does anyone have knowledge in this department?

When i touch phone i loose 4g

Im not sure why but

*#*#4636#*#*

Change band to usa

Immediately fixed issue
[Elephone P9000 Questions & Answers] arlrb:
This code just gives me info, can't change anything.

Do you mean *#*#3646633#*#*?

& then where to select usa?
[Elephone P9000 Questions & Answers] arlrb:
Have a try at this:

Settings>data usage>mobile networks>network operators (will search, might take a minute)>select your operator in the list, in my case 3(4g).

For me it's been solid since, 4g a lot too.
[Elephone P9000 Questions & Answers] mixterz:
oddly enough changing the band to USA is keeping the phone on 4g for me yet im in Ireland on 3 mobile.

had it set to Europe or Automatic before that.

lets see does it stand the test of time.
[Elephone P9000 Questions & Answers] arlrb:
I'm definitely beginning to think this whole issue is a wrong network setting, what I did worked for me (solid all day) - post #10, & I've seen a few do this & it's worked too
[Elephone P9000 Questions & Answers] mixterz:
after a full day it definitely fixed the issue, 4g signal is strong

cant believe they mixed up something like this.

the average novice wont have a clue what to do.

i was on the brink of flogging the phone.

---------- Post added at 03:43 PM ---------- Previous post was at 03:13 PM ----------

Update major issue if you change the band to USA via *#*#4636#*#*.

The 4g data will work great but you can't receive or make calls unless you change it back to Europe.

[Elephone P9000 Questions & Answers] carlx:
As far as I know Talkmobile doesn't have 4G they only offer 3G for now so no matter what you do with the APN you'll never get 4G, also with most MVNO services you will alway need to setup the APN manualy as they use someones elses network in the case of Talkmobile they use Vodafone.

[Galaxy S6 Q&A, Help & Troubleshooting] diabolical1:
Hey guys,

I have been using a 5.0.2 rooted firmware for the longest time possible and it is time for my to update my firmware because of certain battery issues.

How should I go about updating it? I did supersu's full unroot and tried the original software update but I still get the error message saying that my firmware is modified.

Tried out smart switch restore+update but after downloading the firmware and putting my phone to download mode, it gets stuck at 0%, not sure if its my wire issue because its a 3rd party wire, lost all my original wires so far with no more ideas I can come up with.

I am currently downloading my firmwares from sammobile which is taking ages, with the risk of the download corrupting halfway through. Can I flash a 6.0.1 stock firmware on my 5.0.2 and magically everything will work and my phone will be on 6.0.1 and then I can proceed to root it again? My download mode shows that I am using official samsung firmware but its custom. Or do I need to find a 5.0.2 stock firmware then flash it and update from there? I can't find my region's 5.0.2 anymore because its too old, I'm from Singapore by the way.

Any help is greatly appreciated, have been trying for 6 hours to get this to work so far and frankly I dont think I want to go through the trouble of rooting once I update to 6.0.1 because of this cumbersome process just to try and minimize battery drain.
