!!Read post 14 (maybe solution)!! - Strange Battery Behaviour with battery tools

Hello
I have new diamond 2 for three days. It's very good machine, but i've one serious problem with battery. I try to explain the strange behaviour of it:
1) Battery life is too short. I have read in this forum, that battery life is amazing. I dont have this opinion. My topaz's battery life is about 3/4 of a day (standard using)
2) battery behaviour 1 - sometimes i have battery % value another than after restart. For example i have now 50%. When i do soft reset i will have 35%. After second soft reset i will have 42%. Maybe i have problem with battery calibration or something like that. Or ROM is bad.
3) battery behaviour 2 - many times my battery freeze at specific % value (for examlple 40%). At first i though that is amazing battery life. Buuut no. After few hours still was there value 40%. So i tried soft reset and i saw only 16%. I really don't know what is this problem about.
I tried ariel battery bar, which is very simple program and i didn't have problems with it in the past (when i had kaiser). But here was the same problem. Value on Ariel battery bar freezed too. After softreset there was another value. Maybe i will try hard reset in the future....Now i am trying to format battery with process of fully charge and discharge. Maybe it helps.
Has someone the same problem like me?
Detail of my official ROM:
ROM ver: 1.39.479.1 (47382) WWE
ROM date: 04/07/09
Radio ver: 3.43.25.19
Protocol ver: 61.20t.25.10U
Many thanks for help
PS: i had hermes, 2x kaisers in my past, but this kind of problem i haven't had til now. hmmm

Can you list any applications you have installed or is it still original and out of the box with no applications apart from the standard ones?
How did you perform your initial charge ?
I always perform mine by doing a full charge - letting it drain and then back on charge
This happens for the first week - even if it goes flat in the car, I will not plug it in the car charger until I get home and can do a full charge!
Once the first week is done, I charge normally which at the moment has been every 2 days
Did you do something similar?
I have read on here someone else having issues which is potentially down to the battery so it might just be you have a duff battery

thank you for quick response
Apps:
G-alarm
Total Commander
Core Player
Dictionary
MyLight
Nothing special installed. I think at first i must do a hard reset because i must exactly know if this will be on fresh ROM.
First charge - as usually - it was the same like you.
Now i am charging and here is the same strange problem. I am charging now for 2 hour and battery is only on level 50%. So, now i am going to do soft-reset..............few second...................tadaaaa i have 100%. This is not normal. Here is something bad.
But thanks for you help.

I was going to suggest the hard reset route - this would determine if its software or not.
I will say that charging from empty takes a hell of a long time on the TD2! I'm thinking without even timing it, that it is taking around 4-5 hours to charge up ... and thats on mains!
Are you doing a soft-reset while it is plugged into the mains to charge?
Also is it doing this on usb charge (try another cable and NOT the one supplied for the charger)

Have you been using Opera. If so how have you been closing it. Did you go to menue exit or just hit the X? I ask because I found that hitting the X did not fully close it and when I went back to it it was still at the same page and not relaoding my home page.
Also did you set X to close the programs automatically or do you have to hold X to shut the program down?
It is also my 3rd day with the phone but have used internet a lot and the battery seems to be good. I also have been playing lots of games. I have done an initial Full charge and let it drain.... A full charge again let it drain... and last night it got a full charge.... My battery is Full at the moment. Today I have used it mildly for the web.... Like less than 15 min and have played games for about 10. A few calls and that's it. I can say it's doing better than my Elfin has.

Good point - Just for your reference, in the settings menu > advanced settings> System> Task Manager > Button tab
You can set the X to close rather than minimise - I have always set this to be the case so that when I close a program, it does close!

i tried 3 different chargers. Nothing.
Now i am doing hard-reset. Soon i will report.

report-after hardreseting my topaz seems to be fine. Before hardresseting i fully charged my battery. now i am testing it...

hmmm. really interesting. after few hours of testing everything was ok. So i decided to test it with battery applications (ariel battery bar and another tools wich shows battery bar in %.) And here started ainigain the same problems. Can someone test ariel battery bar and test some soft reset? Please watch what happend after restarts with battery %. I tried 10x restart
and everytime was there another value of battery. Sometimes higher, sometimes lower values.....really annoying
Now i have uninstalled all battery tools and i am going to test again if everything is goog...

alkapone please inform us about the results because i kinda have the same problem here, and i am using batti.
i have a lot of applications installed (nothing to do with the battery meter), but i have GPRS not 3G signal, i am closing the programs normally, and i am exiting opera, and so on. i am using it a lot but i think it goes out kinda fast. i almost get 1 day by using it.
can anyone suggest a battery meter that actually works fine? i like batti

Same problems here! Looking at the battery-information tab: After 4 hours of use after full charged the battery is empty..

I have been using dciBattery and qwertyMemory and all seems to be ok.
I have copied the files to the storage card then run the files and set a shortcut in the windows startup folder.
Here is a link to the files
http://freewareppc.com/utilities/qwertymemoryanddcibattery.shtml

this program doesn't have any config ? i don't want to have the memory bar and i don't want to have that gradient thing.

i think i solve the problem - not sure for 100%
hello to all
i think i solved the trouble. when i have uninstalled every battery app, everything seems to be ok. and one statistic - i had today at 12:00(lunch) 20% of battery. after 8 hours standard using of the phone(few calls,sms,internet), my battery told me that it has 10%. i think it is veeeery gooood (8 hours=only 10% decrease of the battery).beautiful.
result - this case showed that some battery apps/tools causes problens with compatibility battery meter vs. these apps..,
list of apps which causes problems (my tests)
1) jimmyes greens battery fixes
2) ariel batrery bar
3) batti
this is not 100% solution. i am still testing.
please write your opinion.

i am going to try finix

I am using it since day one with my td1 and td2 and no problems so far...

Do you think nueDynamicClock and nueClock as well as TweakHD (with it's apparent powersaving options etc) could be culprits as well? I'm on 6 hours standby and 2 hours device usage and I've just hit 55% on my battery (trying out the app alkapone02 just linked to)

i have installed finix batt icon too. batti was battery crazy on this.
i will test tomorrow, i am fully charging it now and i am going to test how long it will last through the week

super. please test it and report here as usually. thanks

Power off at battery 15%

I noticed, a few others, but should be minority has the same problem as mine.
My N1 powers off itself when my battery shows around 15% or so.. sometimes 17% sometimes 14%, never lower than 10%.
I already tried to wipe battery data at recovery or deleting the battstat.bin file etc etc but it is still like that.
Is there a solution for this and any reason for this?
Majority of people's phone only power downs below 5%.
Many thanks

Use the battery calibrator, it's in the development section.

Try bump-charging* then clearing the battery stats
*Charge phone to 100%, unplug it, turn it off, charge again till indicator goes green

actually this i have tried a few times already but it never helped.

My phone turns off at around 19% now after I played with the battery calibrator app. (I set the life at 100%, was lazy to run the full cycle calibration)
Its powerful and probably can fix your problem.

He said he was too lazy to complete the learn cycle, which is part of the calibration technique. There is no sense in trying to pick "pieces" of the process and hope they work, they won't. Start with step 1 and follow the directions to the letter, don't skip anything. I would suggest reading the instructions a couple of times prior to starting and ask questions in the thread if you aren't sure. There are several of us that monitor the thread and will respond quickly...myself during US daylight hours and Temasek in the evening (he's in asia, I think).

Thanks. Wish there was a quicker/easier way.
I'm currently testing a direct way using simple math:
If 1452mAh is 100% how much is 19% ?
i.e. 1452/100*19 = 275mAh (for me)
I've set "full40" to 1452-275= 1177 (the calibrator app's minimum is 1200 so I just set it to that.)

That may work as a guess-timate, but the stock battery comes rated at 1452mAh and stock age is set to 94%, so you would really be setting to 1128mAh unless you reset age to 100%. It really doesn't take that long to set up the application for learn mode...just a few minutes. It does take 31/2-4 hrs to fully charge the phone and complete learn mode if you set the min. charge current to <20mA. To speed things up, just set it to <40mA as you won't miss the little bit of extra juice.

hmmm good point, i never thought of that lower limit. we'll see if we can update the app.
but to answer this thread's question, the age register in your phone is now out of whack, and you need to set it accordinly to allow the battery to go down to 0%. the learn cycle determine's the proper "age" value and sets it accordingly.
you could also guess an age value, say 83%, would be close. but really there's no reason to not do the learn cycle and figure it out.
BTW all these values are stored in your battery's chip, and it needs to be updated to new value.

Quick question:
1) Sometimes even after I turned on the "Detect Learn Mode" my Current occassionally dropped below -200mA (e.g. 160mA) for a quick while... will it affect the result?
2) "Turn off" means turning off the Detect Learn Mode right?
3) where can I see the "Charging current"? Capa.?
Thanks

What if I rotate among three different batteries on a regular basis? I have an external battery charger too. Will the calibration be in any way useful or will it get confused by the changes?
I have my original January 2010 battery, a December 2011 replacement from HTC, and a MOMAX battery that also holds up a pretty good charge.

you can rotate batteries no problem. when you do a learn cycle, the age value gets written to the chip inside the individual battery. so you can swap batteries no problem. just make sure that the correct age value shows up when you swap, cause sometimes the age resets when removed from the phone. just set it manually back to your proper age if so.
we were trying to add "profiles" support to the app so you could swap batterys and it remembers the parameters for each and sets them accordingly when you swap the battery. but i dont know how long that will take...

Okay good to know. I bought this charger:
http://www.amazon.com/PowerGen-Mult...CAT6/ref=sr_1_3?ie=UTF8&qid=1295658169&sr=8-3
And it's pretty neat because I can just position the pins myself to charge any battery I want. I've tried it with camera batteries, Huawei U1250, Moto Milestone and RAZR, and Nexus One batteries. It works really well and it's somewhat future-proof because it will probably work with my next phone's batteries too =)

Battery Calibration

Having seen so many posts on calibration of battery, i have decided to make this thread so to make it easier and useful for you guys. This thread can also be used to share your experiences with calibration and usage of milestone's battery.
Note: This is done using a the motorola milestone 1. So if you're using any other phone, pls ask abt them in this thread b4 you do anything!!!!
Intro:
The calibration of the battery is needed when you want to switch/install roms. This will make sure that the battery is really fully charged, thus preventing the battery life from dropping too drastically in a matter of hours.
I know there are some other methods to help calibrate your battery, but this is the only one I am sure of the steps. Please inform me of the other methods so to share with everybody.
Steps:
1. Before flashing a new rom, use root explorer (with read/write set) to delete the file "batterystats.bin" stored in /data/system/.
2. Charge your phone with it being turned off.
3. After it is fully charged(100%), take out its battery without plugging off the power supply.
4. Wait for a few moments, and a ? sign will appear.
5. Put your battery back in. You should see that the battery percentage increases quickly to 60%. If it increases to 100% with seconds, please skip to step 6.
6. If it stops increasing at 60%, let the phone continue to charge until 100%(takes quite a while)
7. Once it reaches 100%, let it charge for a further 15-20 minutes.
8. Once that's done, you can boot to OpenRecovery and flash your rom!!!
Alternative way of calibration(thanks a lot zeppelinrox!!!):
http://forum.xda-developers.com/showpost.php?p=11803458&postcount=10
This method allows you to calibrate the battery and use ur phone at the same time!!!
I hope this helps you people, because it really helped me!!!!
Note: i m not responsible for anything bad that happens to ur phone. Perform the calibration at ur own risk!!!(though it should be perfectly fine, unless u do something wrong or extra)
Btw, i am just writing things that i assume to be correct, so if anything needs to be edited/added, pls inform me through this thread or sending me a pm.
Credits to everyone (especially pcphobic for his post in http://forum.xda-developers.com/showpost.php?p=11604143&postcount=740) who have written all these in your posts that made it possible for me to gather and get all this info!!!!!!

You should give credits to whom you copied this from.

oh yea i almost forgot.Thx fellow citizen!!!!

And it's good to remove/wipe the battery status data with the charger plug-in as the last step.

thx bnwg, but i don't get you. Mind if you make yourself clearer? Thx!!!!

He's referring to deleting the batterystats.bin file from the /data/system folder.

Yup, got it thx!!!!

rm /data/system/batterystats.bin
For this set of instructions, can the console in the OR be used to perform it?

mods should make this thread a stickie.

Calibrating Without Downtime!
Edit: If this doesn't work on your device, try the Die-Hard Battery Calibrator Script to ensure a proper charge
This is proven to work with Motorola Milestone so I would imagine the Droid as well.
It works with the Milestone 2 but you may need to get the phone booted up manually (step 7) instead of the easy reboot in step 6.
If you have a different phone and this works, please let us know!
You probably won't believe that this will work but try it anyway.
The big benefit of doing it this way:
It's great if you don't plan on changing roms and just want to calibrate your battery without downtime so that you can just use your phone as you normally would.
Note: Be sure that the phone isn't running hot (feel the back)
1. While in Android, charge up to 100% and leave the phone plugged in.
2. Delete /data/system/batterystats.bin
3. Remove back cover
4. Press Power and choose to reboot normally.
5. When the screen goes black and the lights go out, pull out the battery before you get the M logo. It will probably still work after the M logo shows up but that's how I do it.
6. Surprise: The phone will boot up without the battery! - Mine does - every time
Note: Batterystats.bin is recreated when you see the M logo - even though the battery isn't in the phone.
Go to Step 8 if the phone booted up as described.
7. If it doesn't boot up and you see the battery with the ?
..........a) Put the battery back in (you will see 60%),
..........b) Power off the phone (press power until LED light goes out)
..........c) Power on the phone (press power until you see the M logo)
..........d) Remove battery... and watch bootanimation...
8. a) After the surprise of seeing the boot animation without a battery, you will then see the lock screen along with a "No SIM card error" and no signal.
...... Put the battery back in - the SIM card error will disappear, you will get a signal, it will show 60% full and the icon will show the battery charging.
...... Go to Step 9 if this works as planned. If it doesn't, reboot (again without the battery) and use step 8b instead of step 8a.
... b) Put the battery back in during the bootanimation, but after the haptic feedback/vibration (and the buttons along the bottom light up).
....... On a normal reboot, you can actually slide and unlock the phone when you get the vibration during the boot animation. You knew that, right?
9. Use your phone normally while you calibrate the battery
10. Let it fill it up to 100% + 15 minutes or so. When it is truly finished charging, the battery should be cool.
11. If the phone is running hot, weird things can happen. For example, you may get no signal when you put the battery back in or the battery doesn't begin charging (the status bar battery icon doesn't change). Just let the phone cool off and it should work next time.
100% full is approximately 4200mV
As you can see in the cap below, it's showing only 60% at 4241mV (This was after booting up without the battery and putting the battery in)
A few minutes later, still plugged in, it showed 100% at 4225mV and then it went up to 4230mV.
Finally, I then unplugged the phone and I got a reading of 4196mV
Notes:
Now, when I charge it up, it will go up to 4230mV everytime. I leave it plugged in an extra few minutes after that.
I highly recommend Battery Monitor Widget
Batterystats.bin gets recreated if you unplug your phone and plug it in again. So don't do that. Let it get recreated on the M logo (Step 6).
Thanks to pcphobic for a couple of important tips and to pcphobic and sileshn both for confirming that my phone isn't possessed!

Recently I follow Azhad's way to wipe the battery.
When I delete the file (ie. cc_data) under that folder and go back in it, the file will be regenerated. And the batterystats.bin is updated according to the timestamp of the newly generated cc-data file. I don't know if this is the same as the step 6 from zeppelinrox's method.

the myth about the batterysoftware needs some real facts. payce from german forum did some measuring with real astonishing results.

I have seen that article before.. thanks to you of course
I'll quote the conclusion of the first post:
That is, the stone over-estimated the voltage at the battery is full by ~ 60 mV and underestimated the power of up to 100 mV with an empty battery. The intent is well-battery protection (which is good too). It is pretended that 3.0 and 4.2 volts to discharge until it is loaded. In reality, there are more 3.1 volts and 4.15 volts (which by the way of battery manufacturers also better unanimous opinion!).
Click to expand...
Click to collapse
So the reading I get via Battery Monitor Widget aren't that far off and perhaps exactly where they're supposed to be.
After fully charging (showing 4230mV while plugged in) and then uplugging the phone, it will ideally show between 4150mV and 4200mV vs the 4.15 volts (ie. 4150mV) quoted above.
My phone will power itself off between 3150mV and 3200mV vs the 3.1 volts (3100mV) quoted above. Actually, I just checked BMW's log and today it powered itself off at 3162mV after 19.5 hrs.
I found it interesting that you use less power while downloading overclocked versus downloading at stock speed lol.

@zeppelinrox: wouldnt ur steps be the same as doing the calibration my way, just that instead of booting to OR for flashing new rom, we just reboot normally?
@pcphobic: sry cos it would be hard for me to go around checking who posted this kind of info before. well, since u said it, i will definitely do it

Of course it would calibrate either way.
The difference is that I found a way to do it more conveniently.
You can do it anytime, use your phone normally and actually monitor the voltage as well.

The difference is that I found a way to do it more conveniently.
You can do it anytime, use your phone normally and actually monitor the voltage as well.

I am using MS2 and there isn't an option of "reboot" when pressing the power button. Can this be done by using the "quick boot" app? thanks

How?
The phone is not new. Been no this Rom for about a week

I used this quide and all OK...
After the update:
In recovery mode, select options Wipe data/factory reset and also you need to select Wipe Cache partition and also you need to select the option of “Clear Dalvik Cache” after which you need to reboot your device by selecting reboot system now after which all the cache files will get deleted.

You already tried calibrating the battery? And when you install a new ROM you generally have to wait a few days for the battery reaches its normal duration.

the best battery life i have ever had was on MIUI. It was like two days ... no problem. i heard for some guys it was even up to four days.
you are on a gingerbread bootloader, so its no problem to flash MIUI with a *.zip file in recovery. just search the forum here for a good version.
to do:
-glitch kernel
-download a governor ("conservative" or "ondemand")
-two apps from the market: CPU tuner, CPU spy
-search for tutorials for CPU tuner
=> fixed your problems

if you have flashed yout rom with your battery not fully charged, you have to calibrate your battery
And also doing 3-4 full charge

yes, u need to do full discharge recharge cycles 2-3 times... wipe battery stats after that from recovery mode on full 100% charge.
Hope this helps

I have two phones. Both running same Rom but i only use one phone. The other i charge the battery in
only just had to do that since the update.
So the batterys are always fully discharged and recharge.
I didn't know about calibrating the battery ill look into that now.
Thanks for the advice.

Just calibrated the battery fingers crossed this work. Half a day for a phone to last is poor.
Was thinking this is like the iphone
when you guys have fully charged your phones and you go into better status how many how's does it say it has left.
Is it random?
Mine says 40 hours
edit lol now it says 7 mins 40 seconds but battery is still full

You still didn´t gave the time battery needs to settle down. In a couple of days you will see that battery will again last for 2 days easly.
For a better rom that you ask on the first post find it on i9000 development forum. There you have roms with different specs. Choose and test them for yourself and see wich fits you best.
I should say for you to test the Hybrid.

Turning off most app synchronizing (settings » account & synchronisation settings) is making a big difference as well, at least to me. Just disable automatic synchronisation (keep background synchronisation on), and turn it off for all apps. Saves me quite some hours of battery. I'm assuming the update reset all your synchronisation to ON. I'm never using the word synchronisation again, pfft.

hello koooowweeee
Try BatteryCalibration (market) or.
1. Connect the charger to the phone while it is on, and let the load be up to 100%.
2. Unplug the charger and turn off the phone.
3. Reconnect the charger while the phone is off, and leave the task until it shows 100% again.
4. Unplug the charger, then turn the phone, wait for it to boot completely, then turn it off
5. Reconnect the phone to the charger (always off) and wait until it returns to 100%.
6. Disconnect the charger, turn on the phone with flight-+ power to access the Recovery.
Once in recovery, go to Advanced, and make a Wipe Battery Stats, then reboot the phone.
or flash CM7 7.0.2 Kang!
@ +

Well been using my phone all day and battery has lasted so far. Its on 13% now which is better than it was
ill try the method above tomorrow morning and see if that's better
the guide i seen on here was to charge battery to 100% then take the charger out and battery for 90 seconds then put it back in.
Seems to have worked

Poor battery life on second P30Pro

Hello, I had p30pro and was perfectly satisfied with it but from curiousity changed it for oneplus 7 pro and then galaxy note 10+, wasn't satisfied with those devices because of worse battery life than p30pro, I had 8-10h screen on time with p30pro and ~5h with one plus 7 pro and galaxy note 10+. (gsmarena endurance rating is not correct, p30pro according to them has 100h endurance rating and galaxy note10+ has 107h, so I expected battery life to be pretty much the same but its far from that )
because of magnificent battery life on p30pro i changed back to p30pro, but this is second unit I got and battery life is not like on the first one. first one was 1 year old 8/128, current one is 8/256 3 months old and I have like 5-6 hours screen on time with new one which does not satisfy me, battery life is primary reason i got back on p30pro.
usage is the same, same applications installed as far as i am aware
I have screenshot from first p30pro with 8hours screen on time and 25% battery left, it was so great that I had to save it :laugh: and battery life was contant like that
Other pictures attached is from current device, 3h31min screen on time with 38% battery left, so by the time it drops to 25% like screenshot from first p30pro it would be like 4h30min screen on time, big difference. battery life is constant like that
any tips, solutions, suggestions, thoughts?
-i did wipe the cache in recovery
-i tried dark mode
-no app seem to be draining the battery
solutions that i am thinking about:
-wait for 10.1 update for my device and see if there is any changes
-sell this one and get third p30pro (really dont want to do that, I will lose money and time and would be furious if i dont get good battery like on first device )
-factory reset (really dont want to do that, I will lose half a day again customizing and installing everything)
is integrated battery info correct, could there be something /an app that drains the battery but is not showing correctly in battery usage?
FAULTY UNIT?

There must be somethnig draining battery , either delete one by one apk and see if it improved, then you will know which apk was trouble, or hard reset and manually reinstall all apks, do not use backup as faulty apk will do same harm.
Second phone was new or second hand? If second hand you should do hard reset first.., tip for future..

one thing I noticed on screenshot from first device is that I was using only one sim card back then, I turned off second one now and will see if battery improves, altough in Screen On Time thread I see people have 8-10 screen on time regularly with two mobile signals.
"there must be something draining the battery..." can there be anything like that but not showing in battery usage correctly? because everyhing in battery usage seems fine.
both phones was second hand and I did reset them, but from menu, dont know if there is any difference in reseting from recovery?

1. EMUI 10.1 have same battery in some cases may be worse battery than EMU 10
2. Why sell phone if this one is good just need find what eat battery
3. Factory reset thats in many cases fix drain problem but if you wont do that why you not do backup first than make factory reset
Solution
1. Try put all apps in sleep mode settings ---> battery ---> startup apps (there enable sleep mode on all apps only leave apps from where you want get notifications)
2. Dark mode i recommend you use it any time its not save your battery too much but it can help to save battery
3. Use Huawei optimizer app to clean junks and optimize phone
4. Disable synchronizatios
5. Disable GPS, NFC, Bluetooth if you not use it (if you use any navigation than just use GPS when you not need it)
6. I see your Google Chrome use too much battery use instead Kiwi Browser
7. Same about Instagram use light version of instagram or try InstaMod app its better for me
8. Your screen display use 24+ % battery try lower light i have set on AUTO BRIGHTNESS (Tips in settings display set lower resolution)
9. Cell standby try disable mobile data when you not need and btw try put sim in another slot
10. Disable or Uninstall all apps from Google i have disabled Google Movies, Google Music, Google Drive and mayn other apps just disable all apps which you not use
11. I see you are on stock launcher you can try Nova Launcher or Evie Launcher or Microsoft Launcher....(Tips Evie Launcher is one of the lighweight launcher and build for performance/battery i now use Microsoft Launcher which is same as Evie but with little more functions
If you need any info just ask

so I disabled second sim card yesterday and this is result I have now, much better! 1h16min screen on time with 86% battery, which corresponds with about 8h screen on time :good:
can't believe another sim card has so much impact on battery life. my signal is full!
in next few days I will try only 3g or 2g enabled instead of 4g for second sim card to see if that makes a difference.

5 hours & 40% still left, always using data connection. Mainly browsing and watching videos.
VOG_L29D EMUI 10.1.0.126, firmware updated using hisuite proxy

But also any other firmware version was giving the. Same SOT

Yes brightness is always automatic (indoor and outdoor) , i rarely use wifi,
Usage, facebook, YouTube and emailing, and some light gaming.

I think I found your cause of drain. Go to settings, apps, apps, on the top right click on show system apps, then check for hms core. Click that, then on the top right you will se a gear. Click on the gear and carefully untick everything that has to do with data sharing, analytics etc. Check your battery again and let me know mate ??
