HTC Touch HD - Battery Indicator Accuracy - Touch HD General

Hello!
I noticed this morning, following the installation of Atiel Battery 2, that the figure announced i% is unrealistic ... it runs from 4h and the battery is still at 99% ... I did never noticed before because I did not have the info in terms of %.
Has someone noticed the same strange phenomenon ?
A+
Alex

I've noticed the stock indicator seems to take a LOT longer to drain the first 50% than the second 50%, almost twice as long i think.

Cyanogenmod 7 on Nexus One - super awesome battery life, stable wifi!!

I can't post in the Development area yet, so I'm posting it here.
2nd day using CyanogenMod 7, and here's my feedback:
- Very stable
- It seems to have solved my Nexus One touchscreen issue. I've tried CM6 and Enomther before, and this was never resolved before.
- The Wifi is stable with no drop (is it because of the new radio in CM7 ??)
- Super duper battery life!! Even way better than Enomther. By noon, usually I'm at 81-85% with very light activities (browsing, reading emails, etc) and nothing running on the background except Corporate Email and a couple GMail accounts sync. Today it's still 89% and this is fabulous. Note that I've set the Wifi to "Never Sleep". The battery life is SIMPLY AMAZING!
- I can't notice speed differences with ENomther.
- I couldn't care less for the animation or eye candies, but the touchscreen keyboard fix, wifi stability, and long battery life are very important. FYI I wiped everything (data, Dalvik Cache, battery stats, rotation, etc)
THANK YOU, CYANOGEN!
you should judge your battery on a whole days worth of use. The ~5% difference in a couple hours could easily be made by one app or game being run. I'm getting ~36 hours out of my MIUI setup. Though I block and limit many background syncs.
No doubt CM7 is great, huge step from what many android phones are stuck with out there. ps, CM7 doesn't include a radio.

What touchscreen issue?
And it still has the mic-not-working in a call problem, so it's useless if I can't use my phone as a phone.
My N1 has a touchscreen issue since day 1 ... seems to have been fixed in this release.
http://www.lmgtfy.com/?q=nexus+one+touchscreen+problem
Mic is definitely working here. Talked on the phone twice yesterday.
Battery life is definitely awesomeeeeeeee. I have 4 accounts in my N1 (2 corporates, 2 GMail).

My gps loses its signal right after it gets a lock. I'm using CoPilot. Anybody having gps issues?
Sent from my Nexus One using XDA App
Yeah same experience here. What current draw are you seeubf during idle use? I'm seeing 4-5 mA which is great.
I don't think daily usage is a good way to determine battery life.
Best way is to see how much % drops overnight.
CM6 I was seeing 3-7% overnight, CM7RC4 I am seeing 7-20%.
Haven't had CM7 final long enought to check but first night I lost around 10%.
This is with all data off, 2G only and no services running apart from the basics.

Yeah, that's totally the best way to determine usable battery life.
/sarcasm
LOL .. 2G and no services running?
I have GPS, Wifi, 3G all ON. 4 sync accounts (2 MS Exchange, 2 GMail). I have no Facebook sync, however. 3rd day ... still really amazed with the battery life. FWIW, I set the brightness to low (I don't need it that bright anyway) as usual. Same way I usually set it with my 2.2 Enomther ROM and CM6 and stock ROM. Battery life on CM7 is simply AMAAAAAAAAZZZZINGGG or maybe I'm just lucky
GPS locks in seconds, but I haven't done an extensive test with it yet. I'm going to use it (I have both CoPilot and Sygic Aura).
The only weird thing is that ADW Launcher closed and I had to reboot the phone once yesterday to bring it back on ???
Other than that, I'm super duper happy with CM7, especially the battery life

Search for and install "dewonkificator." It has fixed all of my call related problems, along with several others.
I also think that Gingerbread should be given much of credit for the Wifi fixes.
Im finding my battery getting eaten up noticeably faster from CM6 but its worth it for all the fixes/features.
best battery life ever, I pick my phone up ... IT'S COLD!
I've been using Kang-o-Rama 1.1, which is based on CM 6. I tried several different kernels and settled on the wildmonk kernel (2.6.35.10 though I'm sure there are newer versions now), because it gave me a similar excellent battery life as others have described here. I had been using various ROMs before that (those that are close to stock, with a few nice features added) and always had pretty bad battery life.
CM 7 therefore isn't necessary if you want stability (e.g. a phone that always works as a phone, no random crashes etc.) and excellent battery life. I'm cautious about CM 7 (and the soon-to-be-released Kang-o-Rama based on CM7) until the "wonkiness" issue is fully addressed - I don't consider having to install the dewonkifier program fully addressing the issue!
I like to have the latest and greatest, but having a potentially unstable phone is really annoying! Just have to be patient. Regardless, Cyanogen and everyone working on custom ROMs must be applauded for their efforts, don't know what I'd do without them
I have to say I'm a bit miffed about not being able to post in the development forum, which is the main reason I read xda...
Has anyone noticed a difference in battery performance between the first discharge and subsequent discharge cycles on the later cm7 builds? I've noticed that my phone will drains faster the over longer uptimes. The first discharge cycle after a boot discharges at an average rate of 3% to 5% per hour, averaged over a full day. Use over a full day for me is fairly light with some texting, one or two brief calls, and maybe some web and facebook. The battery is usually over 60% in after 8 or 10 hours on battery on that first discharge. After a full recharge, the drain rate on the next discharge seems higher. I've observed that similar use through a second discharge cycle is typically 5% per hour or more. I sometimes struggle to get more than 10 hours use out of the phone on that second charge.
I have noticed the Status Bar app seems to account for an abnormally large amount of battery use. Where's My Droid Power app reports the Status Bar consistently as the top power consumer on the device. Status Bar's power consumption in that first discharge cycle is usually reported around 10%, but jumps to 30% on subsequent discharge cycles. Other known power hogs consistently consume 5% to 6% according to the app. I don't know how the power monitoring app derives its data, but nothing shows up as strange in the Spare Parts battery history. I'm beginning to wonder whether the "where's my droid power" app's statistics gathering might be being baised somehow. It leads me to question my data.
So, does anyone have similar observations on frst discharge versus second discharge rates? Does anyone know what the Status Bar app actually does, and whether it might actually be contributing to higer battery drain? Finally, is there a better power monitoring app i should be looking at to track down rogue apps?

There is a bug in the status bar process. If you have battery percent enabled in the status bar, when you plug in the charger, the status bar process uses 10-30% CPU for the next hour during charging. If you disable batt percent and charge this does not happen.
I looked at the source code and was gonna try a fix soon.
On previous cyan 6, charging temp disabled the percent. Also this slows things down and home screen scrolling gets super choppy.

I do have battery percentage enabled, so that could explain that. Thanks for the feedback! I could convince myself I tried disabling battery percentage before, but who pays attention to the little things when you're having so much fun?
Oh, and an update on the battery discharge thing. I left my Wifi on full time after my last full charge, and i'm about to roll over 2 days runtime with about 10% left. I haven't seen performance like that since i enabled a Corporate Email account.
Yeah I'm getting superb standby battery life on cyan #39 right now. Idle current draw overnight for 8 hours, with wifi on, is seeing 7 mA current drain steadily.
CyanogenMod 7 not working!
I just upgraded to the new CyanogenMod 7 on my Nexus 1 and unfortunately it is not loading. It gets to the CyanogenMod screen, with the Android guy on the stake board and the arrow going around him, but it just wont go passed that screen. It has never gone passed this screen.
What i have tried:
Taking out the battery and restarting it
letting it run for 30 minutes
If anyone one can help me I would greatly appreciate it
Regards,
What kernel are you guys using on CM7 for such awesome battery life? I've tried stock for one week, then redstar with minimal improvement.

Battery seems to drain fast when 50% or less, is this normal?

When my phone is fully charged or has 70 or 60% remaining battery it seems to drain as normal, around 2-5% over a 10 hour or so period...
However, I've noticed once the battery decreases below 50% it drains FAST, why?
Anyone else noticed this? Test it for yourselves, monitor the TIME it takes to decrease from 100 to 50% and then from 50% to 0.
Yesterday I forgot my phone in the car whilst going to work. It was turned on however it was sitting all day in the car.
Once I returned from work I was shocked to find the phone would not turn on.
At first I thought there was a problem or some kind of fault. Once I plugged in the charger it started to charge, the battery cut and the phone automatically turned off!
I remember the phone had around 48% battery remaining, no wifi or 3g or data turned on. It was simply idling...
So the question is HOW can the battery drain from 48% to 0% over a 10 hour period without being used???
Should my battery of been ANYTHING over 50% it would only lose a few percent...
Same thing for me. (Samsung Galaxy Note N7000 - stock Android 2.3.6)
Battery slowly decreases from 100% to ~50% and then ~2x faster.
I charged the note on my computer and then switched to the charger (at ~60% of charge).
I'm no expert of battery charging etc. but just remembered my iPhone 3GS discharging faster when charged on the computer than with the charger.
If it's the same for the note, some cells could discharge faster because charged on the computer.
Can someone confirm this (or not) ?
How did you charge your phone ?

Same thing happnd with me, and charging my phone thru electric charger..
So it seems this behaviour happens to several other Note users, why?
It's a problem knowing that having around 50% left in your battery will struggle to make it through the day with little to no use...
Have you people set the wifi to turn of while the screen is off? This is unnoticeable in the daily use, but increase the batterytime massively. The setting for this is hidden, you have to push menubutton while in the wifi-settings.
Here I thought I was only imagining things about the battery life dropping faster once it has reached 49% or less.

Haha, nice to know I'm not the ONLY one facing this bug...
I can only hope Ice Cream Sandwich solves this battery drain issue.
Hmm, i think i have the same problem, but i'm not sure. Will get back to this thread when i've investigated a little bit.
This may be a typical samsung issue.
I remember when i had the spica , the battery percentage lining in kernel was totally wrong. I think its done on purpose so you would feel like you have more battery life. 75 % of the battery drains slow. And the rest 25 super fast. Can be fixed within kernel.

I believe its just a placebo effect. Battery usage always depends on so many factors its a pain to even consider starting looking for the issue.
Being on stock KK5 not rooted, i cannot report the same. I only see "fast battery drain" at the last 4-5%. If you feel its an issue, could you post the firmware version you are on and the battery stats graph just for reference?
Placebo or not its something I can definitely feel on my Galaxy Note.

When you get the chance, could you post the battery stats graph please? what we should see is a (lets say) 30 degrees angle and at about halfway it gets steeper.
I know its quite hard to demonstrate the issue, but if you lets say use wifi to browse the first 50% in text only sites and then visit youtube for the last 50%, it won't help the test.
A nice way to test it would be to charge it to 100%, then load up a long movie and repeat playing it till the battery is 2-3%. Then post the results.

When the Wifi is disconnected, the 3G scanning will get on. Isn't that defeating the purpose?

Hey there!
I would suggest to load the battery 100%, plug it out, go into recovery and wipe battery stats.
I have to admit that I don´t know exactly what this workaround does, but I read about it in another forum...and it worked for me, my battery status is much more accurate now!

I'm back. I've had the Diagnosis app running for the past hour, and i got some interesting results.
---Wiping battery stats does not help---, a full charge automatically causes battery stats reset.
I full charged mine with the electric charger after fully discharging it without turning it on.
This time i didn't notice any change in discharge speed between 100%-50% and 50%-0%.
Last time I charged the phone it was not fully discharged. Charged it from 30% to 50% then 50% to 75% on the computer, and 75% to 100% using electric charger.
It's just a supposition, but maybe doing several partial charges while using the phone makes the battery % information inaccurate (wrong battery stats?).
[Edit]In this case, wiping battery stats should show accurate battery %. [/Edit]
I had a similar problem, and I think it is to do with some incorrect scaling or measurement.
I was down to 28%, and it seemed to be draining fast even though I was not using it. I rebooted (I love how quick that is after my Arc was so slow). On restart it was at 17% ! The usage graph just did an instant drop.
I also had another occasion where it remained at 100% for 2 1/5 hours of use.
I assume some calibration issues caused the meter to read the battery wrong. I am turning off on the w/e overnight (when I do not need the alarm) to see if a slow (180 mA) charge while off will help. I may even get a decent alarm clock so I can turn the phone off at nights and charge. I spend too much time in the morning checking my email and reading news!
What is more consistent on mine is that when the battery drops to 9% or less the loss is like 1% per ~10-15% and this is with wifi/3g off, phone locked.
I'm back again. I've had some serious battery drain the last couple of days, but i noticed that Auto Sync was enabled. Once i deactivated it it got much better. Pulled the phone from the charger 9 hours ago and i'm at 90% battery left. I've sent some SMS, a few calls and that's about it, but it doesn't drain while it's in standby now, so i'm happy with it.

[Q] LG G2 Battery Drain Issue(s)

Hey dear forum members,
I have my G2 (D802 Europe) now for nearly 1.5 years and I've nerver really experienced that "wow"-effect everyone had with the battery life. Soon I rooted my phone and used cyanogenmod instead. It was a bit better but not for long time and now my nerves are at their end (I don't know why this has not occured earlier :?) so I went back to stock by flashing stock and unrooting but nothing helps. I want better battery life but I don't know why it is so bad.
I get about 6-8 hours of battery life with 2-4 hours of display on time with 50-70% brightness. Sometimes i have 100% brightness but i think battery life is still bad even with 100%. I only use it for calls, whatsapp, facebook, youtube and surfing. I am not even playing games on it. Anyone experiencing the same problem(s)? I was disappointed for over a year but now I have enough time to try things or even send the phone to LG for battery replacement (Root Checker is tripped. Hope it will work anyway if there is no other solution).
Here would be some screenshots of the battery life today but XDA don't want me to do that so I will describe it for you:
Time from 100% to 0% was 7 hours.
Display on time was about 3 hours with 1 hour 100% and since then auto brightness.
In the statistics the display used 39%, the OS 13%, the system 10% and the rest is below 5%
Sorry if my english is bad anywhere in the text I am trying my best.
I hope you can help me with my problem and have a nice day
Small additional info:
I am charging my phone when its about to die before I go to sleep where I would charge it normally. As Example if I use it "too much" for videos or browsing I am charging it while going on with that. And I am not the 100-4% and then full charge person. I charge it when it is possible because it drains so quick. Maybe I harmed the battery over time by doing it but it was also bad when I got the phone new so anyways.

Is my battery degraded ?

Hey guys, How you all doing ?
First of all, I recently got in hands a Nexus 6p! Bought It used (8 months of use), and its perfect, everything os ok.
Then, I rooted It and now i'm using the Android O ROM, with franco kernel.
But, I've been noticed that the battery sometimes drains 2%-3% too quickly. And yesterday my phone shutdown at 18%!
I was experiencing the 2-3% drain on 7.1.2, but not the shutdown.
I dont get that bad SOT, like 3h-4:30 is still a thing for me.
What do you guys think ? Is It bad battery or software related problem ?
Should I consider doing this trick and go back to Android N ? https://www.google.com.br/amp/s/for...-6p/help/nougat-battery-bug-fix-t3559250/amp/
Here is one print from my screen on time and accubattery.

First of all, going "back" to anything is not going to help you. Android 8.0 is not the issue, it may be a degraded battery, especially if you are having early shutdowns. Please open the Health page (Saúde) and post it. That is where you will find your estimated battery capacity relative to a new battery. You should have a few full charges before this percentage stabilizes. Try draining it as low as you can go (or when it shuts off), and then let the phone charge fully until Accubattery tells you your phone is fully charged NOT the phone reporting 100%. It's common for the phone to continue charging 45-60 minutes beyond the phone reporting 100% and you need to keep it on the charger until completely full to get an accurate capacity estimate. Hope this helps. Boa sorte!
Okay. I went back to 7.1.2, early shutdowns got resolved, but the 2℅ drain not.
I followed all the steps of the guide I posted, changed governator, etc..
It have seen to got a little better. Will report back after a few days of usage with accubattery health status.
Thanks!

XT1575 Battery Suddenly Dies at around 30%

Recently, my XT1575 has been suffering from extreme battery issues. First, my phone battery would last about 6h but die (screen turns off with absolutely no warning). Recently however, my phone will last around 3-4 hours before dying. I was running the same flash of AICP before and after the issue developed, and have now switched to crDroid to see if the issue would be fixed, but it was not. I have included a screenshot of my battery graph by the end of the day. Please note that the gaps between the parts in the graph were only about 2-5min in real life, but show up as significantly longer in the graph for some reason. One thing I have noticed is as if the battery completed flat lines when it is not in use. It is almost as if it is forgetting to count down the battery so it thinks it has more battery than it actually has, but something lower level in the phone knows it doesn't have that much so it shuts down. Any ideas?
