WM6 Battery Problem "Solution found and being tested"

Hi all:
i know i have been braging lately a lot on the forums about the battery issue after upgrade to wm6.
BUT- after actually surfing the net for like 2 weeks non stop, i found on several sites a solution which i think would end this "IF" someone has it.
Theoritical Explanation:
it's said that when upgrading to wm6 the battery has to be atleast 50% charged "this is wrong" .
battery has to be 100% charged because for example:
if your battery is say 60% and you upgraded to wm6, the new ROM will mark the 60% as your 100% battery hence why it drains so fast.
that's why you need to charge to 100% first before upgrade BUT the only way to make sure the battery is really at 100% is to remove it and charge it in the cradle separetly until the lid on cradle changes from amber to green.
after that put the battery in your BA and start the RE-upgrade if you are on wm6 already or Upgrade if you are on wm5 or wm2003SE.
you should notice the difference, i'm currently testing it for the 2nd time, to make sure it is the right solution.
P.S. am only a noob so excuse me for the unorganised post.
Pls someone test this aswell
Regards

The battery charge level has nothing to do with the OS, its part dependent.
If i get you right, what are you saying is "if the battery level is 60% on flashing, the new OS will take 60% as being the 100%(maximum) level of what the battery can go".
I think that's wrong.

yes, hence why the battery and BA gets to warm or hot while charging as it cannot exceed the 60% mark which is marked as 100%.
i think it's the only logical explanation

Any battery get warm or hot on charge (or one some type of charge, like car charge).
I may say b*** s***, but after upgrading to WM6, my battery is acting as in WM2003; some software (like HTC home) is draining more, but nothing isn't abnormal; i still get with a 2400 mA a normal day of BA use (PDA+phone).

the ting is my battery was working very good before upgrade with wm5 and wm2003SE but after wm6 this happened, andnever had i get the battery and BA so very hot like ths.
i finished the re-upgrade after charging battery and it's draining is much better, dropped in 1.30 hours 50% but still getting much draining, it used to drain to zero in 1 hour

Did you disables infrared on the new install? This might take some extra power.

nothing wrong with the OS , i believe it's a psycho matter maybe ??? my battery was 94% charged .. i took the device and went on a trip .. 4 hours with TCMP on listening to Mp3s .. i went back home after 5 hours it was 53%. Sounds good for me. 1450mAh and i charge it every 2 days with normal consumption. Maybe ur batteries are getting old because with No plugins installed it's just as good as WM2003SE.

Battery status - Its possible
ahassouna might be onto something. Logically I know this sounds unlikely. However I recall exactly the same point occuring in the smartphone forums when an OS upgrade came about. It was common knowledge that for the HTC smartphone you should have you battery fully charged when doing it. It was widely tested in the forums - www.modaco.com and generally accepted back then that for best perfromance your battery should be 100% when upgrading. BTW - in my opinion this is the best ROM ever released for BA - big thanks and respect to Helmi!

if it's so you never come back after upgrading with non fully charged battery.
I think that's wrong.

Emm let's say u were right, so i assume that the OS wont determine the correct battery level. So logically, when u get a 0% , the battery is shown as empty while it is not. So if u think a bit , when the OS indicates that the battery is empty, it shouldnt turn itself off because in fact IT IS NOT. So if you get ur device to turn itself off without being able to power on again , that means that the OS was right and it was 0% for real. ( Correct me if i'm wrong )

as the Matter of fact, wm6 is slightly 'heavier' than wm2003, it contains more drivers and stuffs. so it will consume lot More resource than wm2003. I think battery draining also closely related to the read/writing speed of your sdcard, how big the capacity...

My SX66 drains equally under all three OS's, Though I must admit I quickly upgraded from WM2003SE to WM2005. Ran WM2005 for almost a full year, good battery drain, WM2006 seems to drain the same thus far
I would have a look at your battery, there cheap to replace on ebay and such.

Slide2Unlock
Do you use Slide2Unlock? I confirmed that the software was draining battery faster especially ver 1.216. I uninstalled it and my battery back to normal.
I hope it helps.

I don't believe that would cause any problems...the OS is independent of the battery. Anyway, my battery use is only slightly higher in WM6 than WM5.
Your battery can be at any level when you upgrade the ROM...I really cannot see how the OS would "read" the status of the battery and set that as the 100% level.
Try running your battery down to something below 50%, then reflash your ROM...now what does the battery meter show? I bet it shows the same as before you flashed it, below 50%.

Yes. In fact every battery has a internal chip for charge controll and status level. OS reads the status of the battery by this chip.

no i don't use it, i finished flashing for the 3rd time with a "3rd battery" Still same problem BUT draiing is less than before but still 1-2 hours max without any calls and drops to zero.
am begining to think my BA went razy for some reason.
P.S. i have no apps or anything installed other than flashing the ROM.

My BA drains normally. I have 2-4 days of standby with occasional calls and usage. The backlight auto-closes in 30 seconds, the power goes off in 1 minute.

Exactly...so the first post is wrong...the OS reads the status of the battery and it doesn't matter what charge status the battery is at when you reflash...the battery status circuit will show the proper charge percentage...

Battery does not charge properly when D2 is off

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.

[HOW-TO] Battery calibration

I've just found that on the desire forum, do you think it will word on ours HD2?
vidler said:
Found this on another forum, I have done this a few times myself (do it whenever i flash a new rom because i always clear battery stats, can't hurt). Have found that it does top it up a fair bit. Before doing this i find my desire will drop to +-93% straight off the charger, however this keeps it 100% longer and i actually get to see the numbers 99-94%
Worth a go in my opinion because it only takes 5 mins of your time and can't hurt the phone... So any minor gain from this process is a win...
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.

I think it should work as it's wiping battery stats in android

im trying it too as we speak

I'm pretty sure that calibration will not work currently in android properly. Cottulla posted a few days back that the battery driver is still incomplete and currently only supports reading battery state and that the write too part of the driver has not been implemented. When the driver is complete and has full read/write battery function this procedure should work better.

My battery wasnt calibrated properly and wudnt charge over 90%. Someone in this forum told me to switch off and charge until green and then switch it on. Now my battery seems calibrated plus i got 2 days of use on moderate use

but ive seen several posts of people calibrating their battery in winmo and reporting better battery life....idk maybe placebo

i will try this too. i myself had an issue today. i'm using chuckyrom right now. i use it at work so i can turn the "phone" off while at work. so it is in airplane mode. i only used the phone today to check the time and played some uno on a break. my battery stayed on 100% for 5 hours. so i turned the phone off, took the battery out for 1 minute. put the battery back in and turned the hd2 on. it was still on 100%. 4 hours later it was down to 94%. i just didn't think that a true battery reading. most days when i have the "phone" turned on at work i only have 10% battery left by the end of the day... just seemed odd to me. idk.

Well, I don't know if this works 'properly' or not but it's certainly had an impact so it's doing something right.
Prior to the calibration I could only charge to 95% or so. Phone now seems to be charging to 100% all the time which is good. Battery life also seems great, not sure if this is down to the calibration or not as I moved to Darkstone V2 (16/08/10) release the day before so don't have a baseline.
FYI, as I type this I'm on 49% battery remaining after being unplugged for 10hrs. Fairly light usage, couple of calls; some texting but quite a lot of browsing and XDA App on 3G and WiFi.
Amazing progress the devs are making. Have been running various builds of Android for a week or so no and haven't yet had to revert to WiMo.
Sent from my HD2 using XDA App
Edit: Couldn't figure out how to take a screenshot without plugging in (and hence losing the 'time since last unplugged stat') - so here's a ropey photo for the inevitable 'screenshot or it didn't happen' remark Seems I've been unplugged for 13hrs not 10... where does the day go?!

Anyone able to do this with mattc Leo + Froyo w/Sense? The charge indicator LED never changes to green.

Yeah, its hard to remember to take a screenshot before you plug it in (or in my case...reboot the phone)
You may want to try BatterySnap...its a free app in the market which gives you a great battery widget, plus a lot of really useful graphs and information.
I upgraded to Froyostone on the 12th...thats why the information is only going back that far...but as you can see, 18-19 hours a day at moderate usage is what I am getting on a regular basis

Power the phone off...then charge till you get a green light (Maybe even for an extra 10 minutes or so)...power the phone back up and plug into your charger. now it should charge up to 100%
I dont know if the battery itself is limiting the charge, or if its just the battery meter that is not displaying correctly...Anyhow, the above method corrects it for me whan this happens on my phone.

Thanks matey . I've only had my HD2 for five days but thanks to the awesome resource that is the xdadevelopers forum, I'm successfully running Android on my phone. :-D

Possible battery trick addressing improper charge issue in 7720 after ISVcleanup

Using Battery Tool, my HD2 on Mango 7720/ISV cleanup regularly charged pretty much 3/4 of total battery charge or in terms of HTC Battery Tool the charges were as follows:
FULL 1230
ACR 935
With that being said I 'd previously run NODO on 2.12 with great reception and the same charging issue. Update to 2.15 with Mango degraded my reception, battery life and preserved the charging issue. Then I started seeing posts claiming that flash to 2.12 in Mango improves the overall experience and one of them literally mentioned the charging issue which allegedly disappeared. Knowing what to expect from 2.12 due to prior NODO experience, I decided to roll it back and see what happens...
First flashed 2.12 over 2.15 with battery approx. quarter down its charge and despite better reception my battery constatly charged only three quarters of total charge. Sooo, after reading couple posts on 2.12 radio, and how the battery charges fully all the way to 100% (using HTC Battery Tool to check this), I finally decided to charge my battery in external charger and than once again reflash 2.12 this time with fully charged battery and...
No more three quarter charge . Will do some repetitive charging to test and confirm but so far it's always charging all the way! .
Hope this helps someone who's suffering the same half ass charging annoyance .
PS: Drawback to this is need for external charger or properly charging phone

Uhm... WP7 might be considering a theoretical maximum, just like android does with it's battery calibration.
Difference is, Android has on-the-go battery index recalibration. If it reaches the theoretical maximum (100%) and the charge is nowhere near 20/10 mAh, it keeps charging and set's the new maximum to the new charge (i belive it has a arbitrary battery units, at least Android on HTC Kaiser does).
What you're saying is, only flash WP7 if you're charge is at, or near 100% on WM6.5/Android Otherwise WP7 will waste battery charge

Even better... In case that your battery does not charge properly there is no need to repeat WP7 install, only reflash your radio .
Yes, you may ask how device radio rom could have any effect on WP7 installation which comes with it's own radio drivers after all, but today I can attest that it does. My phone is regularly charging all the way to 1190 out of 1230 all the time as opposed to post Mango Rom flash value of 935 and all I did was reflashed device radio with fully charged battery .
Appreciate the Android analogy .
PS: I presume that it does not charge full 1230 due to phone not charging in USB flasher mode and during flashing process

Question, on what wp7 phone is our version based ?

I suppose it's HTC HD7 based as far as drivers for individual device components go. After all, people who are getting their new WP7 Roms activated (on HD2) literally tell Microsoft customer service reps that the activation is for HD7...

Hi.
There is no other way then complete WP7 Rom reflash if you'd like to switch actual WP7 radio but hardware level radio driver (OS independent) can be upgraded/degraded without resetting or reflashing your phone . Note, I am talking about radio e.g. 2.12 and more as made available via the link in post #1.
With that being said, if there's any radio on that list that suits you or if you're in possesion of Australia compatible radio then all you have to do turn of your phone, next hold volume down --> power on your device and wait for the rainbow screen to appear (kernel flash interface ). Once your phone is connected to PC, your interface type will change from serial to usb and do your thing as instructed under the radio rom link in post #1. Let us know how do you and if there's anything else that could possibly prove helpful
Regards to Australia

Interesting.....
I was only getting a 75% charge with Mango and 2.15 so i flashed my radio back to 2.12.
After an immediate restart the battery charge graphic then showed 100%. Weird.
As the amber light was on I left the device charging into it changed to green. I then reflashed back to 2.15 and I have been getting a more accurate battery charge graphic ever since.
Ooh and the bonus, my battery is lasting longer between charges. Yey

Are you supposed to charge the device until green before flashing?
How long does your batt. last? On the worst day I had 4 hours batt. time (with BT on and WIFI on).
Today without WIFI and BT on the batt. seems to be lasting something around 15 hours.

I fully charge to green before I do anything nowadays.
I rarely use WIFI but I do have two email accounts set-up which check for mail every 30 minutes. With moderate talk time and two hour train surfing time I'm getting about 20 hours between charges. Which is considerably more than before.

my battery loses 10% on 30 mins, that's so LOL..
I have 7720 with 2.15.. with camera trick..
i'm gonna try the 2.12.. just a question, DO i need to HARD-RESET(by phone7 about screen) after the radio flashing?

Hi...no, do not hard reset your phone at all. Whenever CustomRUU completes the ROM flash procedure, simply close RUU on your computer screen and your phone will restart (you will be exiting the rainbow/kernel USB interface). Mango install will be fully functional just as before you shut it down prior to flashing new radio .
Srry to hear about your battery drain issues...hope this will help to decrease it by a lot.
Let us know

The only solution that worked for me amongst all the options (based on my experience)
1. Tried the camera trick - NOT WORKED
2. Followed the steps below - NOT WORKED
* Boot the phone to MAGLDR
* Select "Reset" option from the menu
* Phone reboots normally
3. Hard reset the phone - NOT WORKED
4. Charge the phone in magldr USB storage option - NOT WORKED
5. Finally, flashed the 2.12 radio, did the camera trick (not sure if its relevant). The battery life has improved dramatically. It lasts more than 24 hours and still running (26% left) - WORKED.

Axon 7 2017G - bad battery indications.

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.

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.

-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
