I am finding it hard to get proper battery stats since Android constantly causes my batter apps to break the stats up into segments instead of giving me the stats of the entire battery usage from last full charge. Any ideas?
I have used AccuBattery, GSM and Battery Bot, and Android does it to them all.
Anyone? Using Battery Bot now and it's not giving me stats for the full charge. It seems to be breaking it up into sessions. Like an hour here, then resets, then two hours there, etc.
I am getting good results with battery widget plus

I've gotten my seidio extended battery and have never really tested it to its limits. I would like to have it functioning optimally. I have the app "Battery Monitor" installed which can calculate the percentage left via the voltage as opposed to the stock battery indicator. I am currently showing 57% via the voltage monitor and 35% via the stock monitor. I have found that my battery can drop to ~1% (according to the stock indicator) however the voltage indicator would be at something like ~30%...my phone would turn itself off at that point in time and I would not be able to take advantage of the reported battery....I have followed directions from: droidxforums.com/forum/droid-x-general-discussion/18216-disable-low-battery-warning.html...I bootstrapped and reset the battery...but nothing. I was wondering if anyone has had any experience in this or could help me out.
Thank you.
I think if you go into the screen where you clear the Dalvik Cache in the recovery menu there's a battery settings function. If i've read some of these posts correctly, that calibrates the phone to the battery. basically re-adjusts the 0-100 range on the phone.
You need to do this when the battery is fully charged.
Draining your battery all the way down will destroy your batteries capability of holding a charge in the future.
Your phone is suppose to only charge to ~90% and cut off at ~10%.
Ultimately this means you are only using 80% of your battery, but it's how Li-Ion batteries works.
If you truly drain it all the way down you ruin the battery.
There are some things you can do to recalibrate the software that determines the charge level of the battery though, like the above post suggests.
I don't know if you're running a custom ROM, but if you are or aren't you should definitely check into changing your phones Kernal to Chad's or IncrediKernals. They drastically improve battery life.
For me, it gave massive improvements for 'screen off' (1% depletion every 1 hour) and significant improvements when using the phone.
Of course I'm using the HTC extended battery, but that was much better than the 3-5% per hour I got before.
hello,
please tell me what's wrong with my xda iis. when the power below 75% and i activated wifi/camera/any apps, oftenly it turn off by itself. also, it often signal loss or cannot make/receive calls. thanxs
I have been noticing something strange. I have gotten in the habit of draining my battery down to single digits before charging in an attempt to keep my battery life up. I usually use netflix on 4g to do this as it does a pretty good job of sucking the juice down quickly.
A few times I have noticed that after I shutdown netflix and let the phone sit a little while that the percentage actually goes back up. For example, I kill netflix at 4% battery left. I set the phone down for a bit and when I pick it back up the battery is at 10%. I have seen this multiple times.
Just curious if anyone else has noticed this and anyone has an explanation for why this happens.
I believe it has to do with the battery meter displaying how much battery you have left based on what you are doing? So when you stopped being resource intensive it adjusted itself.
That's one explanation I have heard.. there is also one that has to do with the amount of current going to the battery.

I can't answer your question directly as there could be multiple reasons. (Battery capacity estimation is tricky business, and I don't know what algorithm they're using.)
But I can tell you that the common belief that one ought to discharge batteries before recharging them is not applicable to modern lithium batteries.
I was (to some extent) true for old-fashioned NiCd cells, but modern Li-ion cells shouldn't be excessively discharged. If you want to prolong battery life it's more important to keep the battery cool. (Lithium cells degrade much faster at elevated temperatures.)
(To contradict myself I have to add that the battery capacity calculation can be improved by discharging the battery completely from time to time - but again, this depends on the battery capacity calculation algorithm they're using.)
I understand the way current battery tech works. The discharge is not for the battery itself. Its for the Android OS. I have noticed that whenever I plug my phone in in the middle of the day, the next day my battery doesn't last as long. In fact the poor battery life will remain an issue for about a week until it levels itself back out. I have noticed this behavior on multiple phones by multiple manufacturers.
You end up going in a circle. You use heavy data one day and as a result you have to plug in in the middle of the day. The next day your battery doesn't last as long so you plug in again. Unless you allow your phone enough time to level back out then it will always appear that your battery life is aweful. Since i've been discharging my battery I am able to unplug my phone at 7:30 am, use it moderately all day with GPS, Bluetooth, 4G on/wifi off with a live wallpaper running. At 11:30pm when its time for bed I still have around 60-70% battery remaining. I find myself having to watch a few hours of netflix on 4g in order to drain the battery so I can plug it in.
I'm not sure if this behavior is a result of an issue with the battery stats file or what but I do know that when I flash a new ROM it appears my battery life is reset to how it was before I had shortened it by plugging in the middle of the day.
many of us have seen the percent rise slightly, its normal. when under heavy load watching videos or something and then you are finished, the voltage gets relaxed and pops up some. since this phone uses some type of voltage calculation to determine percent, it will jump up once in a rare while, typically right after you placed it under heavy load then went to idle.
it's normal..
Hello There my phone is using quite a bit of battery at the moment, these two things are right at the top of whats using battery, cell standby 51% and phone idle 39%, surely this way too high?
my Baseband ends in 56 if this helps
im using doomkernal v10 and darkforest rc2 rom
and my build number ends in 42
is this all correct or do I need to flash something?
The % means nothing really, If you do nothing with your phone then they'll be at the top.
The more you do the less these % marks would be.
However if you have battery drain download something like better battery stats to see what is draining most of your battery.
That is far more accurate and their is a forum post about how to interpret the results etc somewhere on XDA
I have to agree with doncoop in terms of that you shouldn't really worry about those two stats.
All phones will enter the idle/standby phase in order to conserve on battery life. For example: After a full charge and reboot, my phone will last anywhere in the vicinity of two to two and a half days. When I check on the battery stats, standby and idle (typically equal to one another) will have the majority of battery % used (typically in the 65% to 80% range).
Can you improve on that further? I guess, if you decide to underclock your phone or use a LV kernal. But again, going back to what doncoop stated, using a program like Better Battery Stats can help locate background usage programs and how they effect your battery.
From my personal experience and some googling i found out that a combination of juice defender and GSam battery monitor will drain your battery dramatically after some days/weeks (I have experienced it)
I was getting 5 hours+ on heavy usage but today these two apps sucked my battery off and my battery went from 70 to 40 in an hour or two.
After some internet surfing i found out this.
Please confirm

I am also getting high usage from the kernel on the stock rom. Sometimes, the battery goes down even faster than normal, but a reboot seems to bring it back to the usual consumption level.
I have also noticed my phone is awake quite a lot while on wifi, but I'm not sure if disabling it would improve anything.
My battery life suddenly became horrible this morning. Normally I unplug my phone every morning around 6AM, and i dont need to charge it again until closer to 9PM.
This morning, I realized that despite being on a full charge at 6AM as usual, my battery was completely depleted by 10. I checked the battery "app" and it said that phone idle and cell standby were both at 13% usage, and that was the most i had used my phone. it registered the full time (4 hours) of usage for those 2 but it also said that it was only responsible for 13 % of my battery drain each. After that there was google play services.
I figured it was just a fluke, so I reboot the phone and recharged it. Once again, the battery drained in a mere 4 hours. This time it told me a voice call of only 10 minutes length was responsible for 35% of my battery drain, and that having my screen on for a seperate 10 minutes was responsible for 25% of my battery drain. This might be fine and dandy if the actual draining chart showed a steep fall off when i made the call, but that is not the case. the chart is a straight line showing constant drainage with no steep or flat areas. I'm thinking something is definitely wrong and the phone is causing itself to drain. maybe something hardware oriented, since i dont even have very many apps downloaded.
I've literally only interacted with my phone maybe 3 times today, and I didnt even do anything major.
Do you guys have any ideas as to what is going on with it?
I'm CM10, latest stable. not the monthlies. no cpu hacks or anything, and as I said, this problem cropped up this morning. before this everything has been fine.
Please search for Better Battery Stats here on XDA. That thread has quiet a few tips on saving battery drain.

If I hadnt already made sure I was following the tips and I wasnt dead sure that something was the problem, I would not have made this post.
I did manage to figure out the problem by sheer dumb luck and a little bit of educated guessing.
I uninstalled the MyFitnessPal and tried again today. I'm exhibiting normal battery drain now (10 hours and im at 46% with not too much usage of the phone).
If you read the post I made, no apps were showing up as a large battery drainer, and all my stats were reporting incorrect times (13% battery usage for a 4 hour period despite showing me i only used the phone for 10 minutes). So something was definitely wrong. Uninstalling the app fixed the issue though, so for anyone who exhibits this problem, uninstall whatever apps you most recently installed and do a reboot.
I didnt have to reset or anything.
