Hi,
I noticed the following problem on my Diamond 2:
If I turn off the phone for night charge it never shows green in the morning.
The only way to see that amazing green light is to charge the phone whent it is turned on.
Of course I applied the latest hotfix - no use for the off mode charging. And of course I wrote to htc - will not waste your time repeating their suggestions.
And I am not happy with my phone battery life - it hardly endures one working day - lets say - 10 hours...
ROM - Official, yet.

I never turn my phone off so the green light problem never arises. However I will check and see if occurs.
As for battery life, you will need to give it a few weeks of use before you see maximum battery life.
Make sure you don't continually discharge the battery (better still keep it charging whenever you can) and you should see improvement over time.
Unlocking and replaceing the ROM can also have a significant effect on battery performance as does the Radio version in use. That's going to need some work on your part but the improvements are there to be had.
Some apps that are in common use are also power hungry and can cause a significant drain on power.
And if you install your apps to mem card then again that uses more power than installs to phone storage memory.
You can also turn off any unused background apps and processes.
Only turn on Bluetooth and WiFi when needed.
All these things help.
Personally I carry a spare standard battery with me at all times and strangely since I bought it I haven't needed to us it. The placebo battery effect?
Thanks for the answer.
About the battery usage conseption:
You suggest that I plug my phone each time when possible?
I thought that as the battery has XX recharges according to the specifications it is not good to charge each time whenever you got AC or USB access
I started to follow your recommendation anyway.
For example however - my laptop is never (when possible) with battery in it. I use the battery only when necessary, becasue in the user manual is written that has 300 cycles of recharging. And I always wait until completely discharged before charging. That is how I began treating the Dimond, too.

With Lithium Ion batteries the "quoted" numbers of "rechage" is is an approximate equivalent to give some idea of life expectacy.
It's a hangover from the old NiCad battery days and is not really very helpful when applied to Lithium Ion usage.
The most important aspect of LIon is it's ability to hold it's voltge at max current for longer than other technology. It does this best when well charged and maintained at near max as possible as often as possible. The downside is it's life expectancy which does deteriorate over time.
If you require max daily useage then max charging whenever possible will give you this and you will have to accept that the battery will at some point loose it's charge retaining capabilities and will have to be replaced.
For most of us that's the most important thing.
This is not a battery issue, I believe that this is a software one.
I noticed this morning, having left my phone on charge, and 'off', all night, that the indicator light was still red. When I switched on the phone, it showed only 80% charged.
Having seen this before, I carried out a soft reset, the battery indicator then showed fully charged.
So the battery is charging fully, but the battery charge indicator is showing less than that.
i currently own 3 units of s200 and have flashed them with cooked roms. however i have discovered a very disturbing fact about almost all the ccoked roms here - the battery driver is screwed up. i ended up changing 2 of the 3 phones battery because it only charges till 55% and 74% respectively, the 3rd phone charges to 95% and is stuck there
2 of the devices came from a same build september 2009 and the third phone is from jan 2010( i guess because it only says on the service receipt).
am i the only one who is experiencing this or there are more of you who had been infected by this bug?
i finally flashed all three phones with 3.03c official for malaysia/singapore
one more thing i noticed, all the roms effected were using somekind of tsowens taskbar icon as well as using non acer dialer.

Which Custom ROM did you used?
used a couple of kubino's
arto's latest
one of yours. (if i remembered correctly... i have to check my download folder)
additional info, the battery will get stuck on the last maximum charge before flashing... lets just say i have 55% batt and i flashed a custom rom... after flash, the battery will not charge more than that.
(it is safe to say that you must flash the phone in 100% batt... my bad, i flashed as soon as the charge goes over 50%... pardon my obsessive flashing disorder)
i even have left the phones connected to the charger overnight and in the morning it is still displaying the same level of charge (+ over heating = almost dead battery = buying 2 mugen 1500mAh's)... at first i thought it was a minor battery update lag bug, but the phones will die within 5 to 6 hours. sometimes they will be switched off for no apparent reason
i seriously want a 6.5.x rom running on all 3 devices because of the touch friendliness but the fact that it gives me battery errors turns me off.
just hope i can use custom roms like i used to on my previous htc devices.

Well your battery is broken.
I have already flashed with only 30 % of battery and nothing happened. Have also flashed my Phone over 200 Times in the last 6 months, in the last 3 days over 50 times - and the battery is still functioning without any problems.
On my Sencity ROM it holds for 2 days without loading.
thanx for feedback
i think i'll experiment on a few more roms. as far as my devices go, the problem was rom specific where flashing the stock rom eliminated the issue.

In my opinion, it is the issue of your battery, not the driver. If you use the original battery, you will find it works fine! The high capacity battery maybe need the special charger. Maybe just because the phone can not recongnize the battery's capacity.
By the way, I found that the battery does not work well with the new style roms. The battery always exhausts faster than the old style rom. For instance, the rom 23140 exhausts battery faster than rom 21057. My battery can stand by for neary 4 days with rom 21057, more than 3 days with rom 21895 or 219xx. But it can only stand by for about 2days with rom 23140 or 28xxx.
well the drivers are just ****ty
i searched thru the forums to find out what is missing... and i find then post that says new roms = new base drivers = recalibrate battery
guess what, i recalibrated my battery even the "broken" ones. now all are working perfectly.
the catch
1. recalibrate all batteries
2. delete any battery icons / taskbar enhancement (can be reinstalled after all this)
3. use any regedit find string "state" without the quotes. find "battery", and change all values to 0
4. charge batteries without turning on device, wait till light is green.
5. turn on device, make sure battery % is showing 100%
6. take off batteries, wait 10 seconds, reinsert battery
7. push vol+ and vol- and press power button (hard reset device)
8. voila... perfect charging battery
tested for 1 day already. the broken battery were not broken after all, its the battery driver. it will not make changes or detect changes from the battery because its from a different base driver (even if the drivers were said to come from official 3.03c bla bla bla.
sorry mates.. its not my batteries. if just one device its understandable. its from 3 seperate devices (one is actually my girlfriend's) so i made a conclusion that even roms cooked from same base will actually have a flaw that can kill your devices......... slowly
bottom note - only flash your phone at 100% batt and reflash stock rom in between flashes.
@ sinocreate
BTW the mugens were bought to replace 2 ORIGINAL batteries that had been damaged by the roms. do read the post carefully.
i think you are competent enough to understand my simple english.

In your step1:recalibrate all batteries. I just want to know how to recalibrate the battery?
I remember that the system can recalibrate the battery automatically from maybe WM6.1 or newer core...
recalibrate
set backlight to maximum
turn off powersaving
let the device run until it dies by itself
take out battery for 10 seconds
put it back in
turn on device
if device turns on - let it alone until it dies again
if the battery have fully discharge, hold the power button red led will blink
once you know battery is fully empty, you can
a. charge using the original acer desktop charger
b. charge using a phone with stock rom
c. charge using your phone (make sure phone is off until fully charge)
wait till green light. then you're done.
the premise of this.
1. every battery has a chip that tells the phone and power management system that either it is empty or charged (voltage level, temperature etc)
2. Flashing custom roms abrupts this transaction of info from battery to power management causing innacurate reading.
3. new base driver will detect different battery level, some are ok and some are not, unfortunately in my case it has a serious error.
4. recalibrating is just a remedy to make sure that both phone and battery starts reporting on power drain from 100 - 0
one more thing, if you think your phone is affected, charge at a minimum of 8 hours (sometime the green light will come out earlier due to the fact that it is not accurately reporting the battery charge)

Where did you find that? Because that is for the HTC Devices. The ROM's for the HTC's use different battery drivers.
For our Acer device there are drivers 2.002 and 3.003. None of the kitchen Chefs use the old battery drivers or replace something in the OEM package.
So, if I say to you that my ROM has 3.003 drivers then be shore - there is no difference between my ROM and the official Acer one.

yes there is a difference. new builds brings new improvements/change towards many features including power management. i am sure you have been around long enough to have experience improvement in kernel and memory management as well as power management.
driver 303c was specifically made for the old builds. not 6.5.3. so i guess the best way to be sure about the battery issue is to recalibrate. it is safe and it is free.

Yes, you are right. If the battery isn't functioning as it should - then it is best to recalibrate the battery.
But normally this won't happen if you first full charge the battery when you buy a phone and then turn it on.
thanks
brainmaster, nice rom by the way, thanks for cooking. i'm using one of your rom now, i recalibrate and getting a good battery life good battery life.

Hello everyone,
I recently bougth (1 month) my samsung google nexus 10, and when i connected him, at home, i see that it comes with 4.2.
When i connect it to my network by wifi, automaticaly upgrade the system , now i have 4,4,2 KOT49H.
My problem is, my tablet rarely popups the low battery notification. I tried to install some app i find in google store, and i find this one, battery notifier bt free 99, where i can set a custom sound for low and full charge battery.
But no way to work neither.
I install this app in 2 other devices android (1 tablet , 1 smartphone) with android 4,2.2 and it´s works.
Do you have also this problem with yours google nexus 10, or it´s just me.
Thanks in advance.

Hi,
Sorry but I don't quite understand your problem. Is it only not showing the low battery? Maybe it's the case that it doesn't even get to 15%, which is the first notification. My tablet, for example, is shutting down on 20%, so it doesn't show the notification. If that's your case as well, then you should recalibrate your battery (I need to do with mine as well ).
If that's not the problem, then I'll need to examine further... For now, just make it clearer for me .
~Lord
I had to buy a new battery mine would always say 100% but when it was dead the tablet would shut down I could recharge but still always reported 100 are you having the same problem? Mine was brand new from eBay he sent me another tablet and said I could send my old one back or keep it for 75 so I did that a battery is around 40 on eBay and is easy to replace. For me anyways.

hey my battery on my nexus 10 is not acting up. It will charge to 100% but soon as I unplug it, it will shut down a few sec/mins later and while completely off it show that the battery is either 0% or 100%, but wont boot up pass the animation screen. If I leave it plugged in for a while it boots up all the way and then it shows that its at 0%. However after only a few mins it will show that it is 100% working. So Im not sure if its the actual battery or some sort of corruption between the actually battery level and the data file that shows u the battery level. The funny thing is that I can go in and navigate all through Recovery Mode with now problem....even when the tablet shows that its at 0% and wont boot up pass the animation screen. So Im really confused. Any suggestion or thoughts? Also if i have to swap the battery how easy or hard is it?
Battery at 100% all the time

I have the same issue: battery stays at 100% no matter what I do. It is a NEW REPLACEMENT BATTERY which I got over e-bay, to fix the old one which had the erratic behavior as decribed above (either 100% or 0%, not even booting up). I see 100% charge always, thoug it does react to AC (un)plug. What is the solution here? There is buch of people writing at forums to replace the battery, but it was not the fix for me. Is it possible that the replacement piece is broken as well? Or is it software? Or some pther hardware module, which may be replaced?

Maaann Ive done so much research on this and couldnt really find anything. I have no idea what the problem is....one part says its the battery....another part says its something else.....I think theres a miss-communication between the battery and the charger (I think). They are not speaking the same langue. But thats just my personal opinion. I took my tablet apart using a friend tool kit to see if maybe discounnecting the battery as well as the other port would do anything...but nope...nothing happened. I still get the same results. I was then forced to call Google...who ended up transferring me to samsung becuz Im not longer on warrant (time expired). Samsung said for $108 they should be able to diagnose..and fix my tablet (including shipping both ways), provided it doesnt have water damage or any physical damage. (which can lead to paying more money). Im just going to do that bcuz at least I know the work will be guaranteed. Im a bit nervous bcuz my tablet is rooted and has a custom rom on it, But at the same time it shouldnt matter bcuz im not in warranty anyways, So hopefully i'll be good.
All that being said.....I really dont which is causing the issue.
Guys I have a problem for the battery of my notes 3. when loading the phone off me arriving at 100% then when I go to turn down towards 95% as ever ?? I also bought a new battery and always makes the same joke then I consume a lot. For example when I go to school not using it almost never goes down by 40%.
I have to bring in warranty you think?
Do a factory reset to rule out software problem?
Some further information would be great.
1. How old is your phone?
2. Customrom or stock? IceCreamSandwich, JellyBean, Kitkat or Lollipop? If customrom is it stockbased or cm/omni etc.
3. Did you charged your phone always using trustworthy chargers?
4. Do you use original spare parts?
5. Did you try to calibrate your battery? (never had a prob. with battery calibration, but you never know..)
6. Do you have a batterylog? Maybe there's a battery draining app.
Software related problems can be solved doing a factory reset or, if this doesn´t work, try to update to latest available android version.

boys then the phone has just 7 months old and I have always used products samsung original. use as OS 4.4.2 kitkat officer and I have done
several times factory reset etc but I always have the same problem.
as calibrations battery not having root permissions I never made.
do you have mp3 files on your Sdcard?i had a battery drain once because of an audio mix service.the cause was bad mp3 files.if so take a backup of them,delete the ones on your phone,see if the prob is gone or not.
I am willing to help but honestly i cant understand your english. can you show us the battery usage?
Just to clarify it,
you charge your phone untill it reaches 100%.
Then you plug it off and it instantly drops down to 95%
You did a factory reset and the issue persists
If this is correct it seems to be an issue with the charging controller. If you never modified your hardware/software (tripping knox or whatever) sent it to service.

Don't quiet understand what your saying?
You having issues with your battery draining quickly?
If so download Battery Doctor and it will display apps using your battery.
Try turning off bluetooth, wifi, any connection apps and see if that helps.
Your need to narrow the issue down.
Hello, I worked on Nougat B09 nad now B10 as Slim 4 and Slim 5 ROMs version from this forum. My problem appeared suddenly with the following sympthoms:
1. Battery lasts on 100% during normal usage discharging mode, doeas not show proportional battery usage and drop,
2. Battery can drop suddnely (or very fast) to 50 % then switch off,
3. Battery shows inconistent indications when charging in "phone off" state (eg 1 %) or when charging in "phone working state" (eg 17%) or vice versa,
4. Due to verys fast drop of indication, there is never "the 15% level" detected and the phones does not enter "Ultra power saving mode" what worked pefrectly before.
5. When battery is 1% and the phone is switch off, it needs relatively long (eg. 20 min) time to be able to boot and work again, if not - it boots, shows there is still 1% battery and switches off (in fact battery maybe already is charged partially and could work, but there is wrong 1% indications and system decides to swoitch off)
6. Soemtimes phone charges very long and still shows eg 30%, but when switched on, the battery indicator schows that is charging and battery level grows very fast, eg 1% per second or two, as it would like to achieve proper indication as fast as possible.
Overall I think battery performace is not so good, the only problem seems to be that system is given wrog batterly level indications.

Can it be hardware problem? I installed Slim 4, Then Slim 5 with and without Magisk? Is there any software partition that can be corrupted and causes bad battery indications . Should I try to lock bootloader and come back to full stock ROM? (I only do not know which boostack to use, the rest I can handle).
I am using brand new stock charger and cable in very good condition (from this model, out of the box yesterday) , other good cable and fast charger from other phone (used so far and worked very well) as well as power bank with QC 3.0 so there is not a problem of cable or charger.

-Never lock the bootloader unless you're on stock ROM with stock recovery and unrooted
now that we got that out of the way, you should:
-install a battery calibrator (the one by nema is pretty good). this will delete the calibration files.
this will cover the software side
-install accubattery and charge from 0 to 100 some times. This will tell you how much capacity the battery has
this will tell you if it's a hardware problem

Thank for Your reply.
I planned to do it as follows
1. Make a backup what I have with TWRP.
2. Perorm full wipe in twrp
3. Flash stock bootstrap and modem with TWRP (I do not know what is boostrap since I came here from LeEco)
4. Boot in fastboot and flash stock recovery
5. With stock recovery install stock ROM Nougat B09 (B10 seems a little bit worse)
This will guarantee I'm running stock ROM. Locking bootloader is not needed, only if I would like to return it to Gearbest for warranty.

Ok I will try. Did you mean AccuBaterry app from Play Store? Should I use paid version? Did you mean charging from 0 to 100 several times in turn or just do it from time to time? How to deduce about bettery? As I mentioned the time it works on one charge seems to be good, only indicator is showing bad values causing the system is making wrong decisions. The AccuBatery will probably take the battery level valu from the same source as system does...
Sory for double post. I planned to edit it and then remove the last and to merge the two.

First of all, there's a much easier way to return to stock :laugh: either download the stock ROM from the Download Center (the twrp flashable ROM, e.g. B10 bootstack and stocksystem) and flash them, or use EDL Tool by djkuz and install a stock file.
If you won't relock the bootloader then there's no need to install the stock recovery! EDL Tool will install the stock recovery though. or you can download the zip from the download center and flash it
the free version of Accubattery is enough. And no it doesn't take the values from the system lol... it measures current on charge and time, and calculates capacity with it.
I mean charge from 0 to 100 several times, i.e. charge to 100, use the phone until the battery dies, charge again. After 3 times the result will be pretty accurate

Well, I am not sure thi will help me. As I already mentioned the problem is bad indication, not the battery life itself. Eg ot shows battery 100% but still charging, so if I think my battery is full and dosconnect the charger it can discharge fast.
If I think about some hardware repair is it battery that shows wrong values or charging module or either component? Has battery inside any chip controlling it? When I can read about it?

Well I also don't believe it's that, but i just wanted to get it out of the way, who knows. Did you try the battery calibrator? It helped me once with 30% shutdowns
