This started on suiller's ROM guide, but I feel it's really OT so I should take it outside.
I've had battery issue ever since I got the Diamond. With moderate use (maybe ~15-20min of call per day, email check every 30 min, moderate web browsing) the battery level can drop by ~ 15-20% per hour on average. This means the battery would only last 5-6 hours without charging, which is not good enough to last through a day.
I first looked at whether the phone has any serious battery drain application, and it doesn't. With BatteryStatus I see the battery drain is ~ 100-150mA with GSM on, BT on. When I'm downloading email, or browsing the web, it does go up to 200 ~ 300mA briefly, but that is only when it's transmitting / receiving data. In standby mode with screen off it drains less than 50mA. These numbers seem pretty typical from my experience.
And here's the weird thing - on a typical day, when I wake up, and take the phone off the charger, it can drop from 100% to 93% within 30 min. On the way to work, when I would browse the web lightly, it can easily drop from 93% to 80-85% within an hour. That's pretty bad battery life.
Yet there are instances when I've been browsing the web, or playing MP3, or using YouTube for a good 10-15 min, but the battery level would not drop.
I figure maybe the battery needs to be re-calibrated, so I decided to discharge the battery and recharge it. I know this doesn't help improve the battery life of LiIon batteries, but I was trying to recalibrate it.
What happened, when I was discharging the battery, was I found the battery drop was very quick from 100% down to ~ 50%. From that point on, the battery drop is much slower.
And from 50% to 25% the battery seems to last forever. The most interesting thing is with the battery down to 15%, I did a lot of 3G web browsing, listening to MP3's, turn wifi on, and that 15% of battery lasted a good 3.5 hrs with heavy use until it's so low the phone stopped working.
The whole discharging process ended up taking 10 hours, and that's with HEAVY use for the last 3-4 hours too. That's actually acceptable for battery life (not great, but at least it'll last me through a day outside with moderate use) and obviously doesn't jive with the 15-20% drop per hour when I'm operating in the 50-100% full range.
When I'm charging the battery, I also noticed the level went up from 0% to 70% very quickly ... pretty much over 40 min. BatteryStatus shows it's being charged at +600-700mA.
As the battery gets full, the charging is much slower ... BatteryStatus shows it is charging by ~ 100-200mA only.
With the battery level up to 99%, it took almost forever to finally get up to 100%. I think it took at least 20 min.
So after a full discharge - recharge, I used my phone as normal this morning to see if it's been calibrated, but nope. It still drops from 100 to 93% within minutes of doing virtually nothing, and easily drop to 80% after an hour ride to work.
Does your battery perform the same way? Should I replace my battery? Or is there a way to properly calibrate the battery?
btw location and reception has nothing to do with it. I have good to excellent reception throughout this test.
I'm having the same problem but not with every rom (don't know wich ones, tested almost every rom hero) So is this a piece of software wich shows the live that doesn't work ?? or is it the battery ? As i can see it it's depending on rom thus it's not hardware
But hey I'm n00b
i've noticed that a soft reset or power up will use 3-7% of battery depending on the weather (what else could it be )
don't have the ability to discharge but i agree that in many cases the battery usage drops drastically & there is no reasonable cause
hope someone can figure this out!

1. discharge the battery completely (by playing video, audio, etc.)
2. Remove the battery and wait about 1min then place it back (do not power on the phone)
3. Full Charge the phone, wait when LEDs stop blinking (do not power on the phone)
4. When fully charged - remove the battery (do not power on the phone)
5. Wait about 1min then place the battery to the phone and now you can power it on.
If battery is more or less OK it will re-calibrate.
I hope it will help!

Thanks. I tried those steps yesterday and my phone is pretty much behaving the exact same way after the battery cycle.
After all the steps, the battery shows it's 100%. I unplug it, and it drops to 97% within MINUTES literally. Now I plug it back in, and it takes forever to get from 97% back to 100% (> 1hour)
I think it may be a battery problem and not a calibration problem. The drain averages ~ 120-150mA when phone on, screen on, no data, and below 100mA with phone on in standby mode. That seems pretty typical? I'd think the battery should last longer than 8 hours (till it completely dies) in that case.
Where do you guys suggest I buy a new battery for the Diamond (other than HTC directly)? I bought one from DealExtreme but the battery runs ~ 10C hotter than normal all the times ... I don't think I want that as my primary battery.
If you get through a full day with moderate-heavy use on your battery, I say that is normal and good battery life on a Diamond. So, why bother that the percentage is not proportional? I would not get a new battery for this since the problem is only in the reported percentage, not the battery life itself.
I've had plenty of cars that went from full to half tank on the meter significantly faster than from half to almost empty. You know about it and adapt to it, simply.
Hello !
I'm understand you, i have a ELF (Touch P3450), and a Diamond, the same problem appear for the two phones!
Every Morning, when i disconnect from charge my diamond, my level battery go to 93% in 10mns without reasons (One sms, no 3G, no Wifi etc).
My battery go down to 50~70% around 14H (2H pm), and stays at this level for many hours (4-5hours ~), i think it's not a problem with our battery, but a dysfunction of the sensor battery, which shows wrong data =/
By the way, that problem doesn't appear every day, for example, today my battery has that level : 83% (15h43), so today it has a good level.
Since i have flash that ROM : http://forum.xda-developers.com/showthread.php?t=521941, with radio 1.13.25.24, i have less less issues with my battery, it's more stable!
That's all, hope that helps you.
Ok guys, I've made a few discoveries that I figure I could share with everybody. Maybe you'll find it useful.
Last week I went on a trip and turned off the data connection while I was out of the country. Instead of letting the roaming charges kill me, I was relying on wifi to check emails and browse the web.
I ended up checking emails just as often, because where I worked had wifi AP.
Now, I could usually get 8, maybe 9 hrs out of my battery with moderate use before it's completely empty previously. So I was very surprised to find that with a similar usage pattern, but using wifi instead of EDGE/GPRS I still had 30-50% battery left at the end of 8-9 hours day everyday during the trip. I know data uses a lot of battery, but I always thought wifi drains even more, so that's quite a stunning discovery.
Now, I don't think it was due to wifi draining less than GPRS/EDGE (can't be true), so it must be something else. In trying to figure out what made the difference, I did a bunch of tests after the trip, and this is what I find-
1. Data channel dis-connection / re-connection is BAD
I used to always set my phone to auto-disconnect data channel (EDGE/GPRS) after 5 min of inactivity, in an attempt to save battery. What I found, was keeping the data channel open does NOT actually drain more battery than leaving it off at all. Transmitting data drains battery, but not leaving the channel open. However, disconnecting it, and re-connecting it all the times actually drains quite a bit of battery. I set my phone to check email every 30 minutes, and then there's also the odd weather forecast that needs data channel. In a 9 hrs day, that means channel disconnection + reconnection of about 40 times.
The last couple days I have left my data connection ON all the times, and I actually get more hours out of my battery. My battery used to drop ~ 10-15% per hour with moderate use. By keeping the channel on all the times it's been kept to under 10% per hour!!! I've only tested it for a couple days. I'll report more on it once I get to test it for longer, but the idea that 'keeping data connection off when you're not using it to save battery" seems to be a complete myth. The opposite actually saves battery!!!! And as a bonus, I don't even have to wait for the data channel to connect when I need it!!
2. Recycling the radio is VERY BAD
Everybody knows 3G is a real battery killer. However, similar to EDGE/GPRS, keeping the 3G channel open does NOT drain any more battery than turning it off, or turning on EDGE/GPRS channel. When the data channel is idling, it doesn't matter whether it's on EDGE, GPRS, 3G, or even completely turned off, the battery drain is close to zero in all cases.
Now, you do see a 1.5 - 2 times battery drain with 3G compared to EDGE/GPRS, so I've always turned 3G on only for web browsing or watching YouTube, and use GPRS / EDGE for regular emails update. The thing is though, if you're not transmitting much data (which you won't for regular email update), the difference in battery drain is minimal. SWITCHING between 2G and 3G though, requires a radio power cycle (turn off then back on to switch frequency) and THAT drains a lot of battery!!!
So if you're often switching between 3G and 2G, and you only transmit little data in 2G mode, you might actually be better off keeping it in 3G all the times instead of forcing the radio to power-cycle all the times.
I've tried keeping it in 3G all day long and I noticed minimal increase in battery drain. However, there might be another reason you want to consider - RADIATION. 3G not only drains more battery than 2G, it also transmits at a stronger power than 2G and as a result create more radiation. For that reason, I'm still keeping my phone to 2G for email updates and what not, and switch to 3G only for web browsing. For radiation you may try this thread if you want to read more about it.
3. VGA screen is a REAL battery killer
I do quite a bit of reading on my phone (ebook, on-line magazines etc) and reading ebook was never a battery concern in my days with the Touch (QVGA screen).
That's why I was quite surprised on the Diamond, reading the ebook for 1 hour, with EVERYTHING else turned off (GSM, EDGE, GPRS, 3G, BT, wifi), my battery level went down by 12% in ~1 hour.
The VGA screen drains a lot more battery than the QVGA screen. Now, if you need to use the phone you need to use the screen, there isn't much of a choice. It does make sense, however, that if you're using the screen for a while (like reading ebook) switching from a high brightness level to a lower brightness level.
Oh, and the auto-adjust brightness thing? That doesn't help you save battery at all. This is because it polls the light sensor every 2 sec (default value, but you can change it) and adjust screen brightness accordingly. This mechanism drains battery in itself, and in most cases end up using more battery than keeping the brightness constant at a low to medium level.
The auto-adjust thing is cool, and in theory it sounds like it can save you battery, but unless you constantly set the brightness to max even when you're in a dark environment, disable the auto-adjust and just set it to a constant 50-60% instead.
These are the few things I've noticed and I'm still trying things out, but over the last 2 days I've seen a significant drop in battery drain. I would be lucky to go through a 8-9 hrs day with moderate to heavy use before, the first 2 days I tried this I still had 60% battery left after 5 hrs of moderate use. The Diamond is very weak on battery life so every bit helps! I hope these tips are useful to you!
Thanks for your share

It's exactly what the charging process is supposed to do.
Read more here:
The charge time of most chargers is about 3 hours...
Increasing the charge current does not shorten the charge time by much. Although the voltage peak is reached quicker with higher charge current, the topping charge will take longer.
Some chargers claim to fast-charge a lithium-ion battery in one hour or less. Such a charger eliminates stage 2 and goes directly to 'ready' once the voltage threshold is reached at the end of stage 1. The charge level at this point is about 70%. The topping charge typically takes twice as long as the initial charge.

Great initiative. Just need more people to help report their battery life, as there seem to be quite some difference among some peeps.
Yea I know, I need to find some other tests, Any suggestions?
Not a suggestion, but a question : When you go to the *#*#4636#*#* menu, what is your battery voltage ?
Many report 4200 mV after 2.2 update, but I only get 3890. I know it's not much, but still...

Has by any chance anyone made such test under Eclair?
Btw I've noticed that if you use task killer you can save battery. Apparently there are some apps that even when closed keep eating battery. But I really have no proof of it (and have no time to conduct tests). Maybe someone can help me?
And I also suspect that Chrome to Phone eats battery if you don't press "disconnect" even when you don't have any Internet connection enabled. But that's another thing I can't prove.
brief tests - unconclusive, eh
I never thought that battery percentage is accurate enough to perform these kind of test, also didn't have much time to do it (so basically % never changed in 15 minutes timespans). Anyway:
* started at 21%
- Everything off (screen too)
- gmail push on
- good (3-4 bars) mobile connection on 3G
- no 3G data connection
- Wifi on - sleep policy -> always on
- Wifi router is about 1m far away from phone
15 minutes later
= still 21%
next --------
* started at 20%
- same as before but
- wifi off
- 3G data connection on - mobile data connection NOT always on
15 minutes later (19.43)
= still 20%
next --------
* started at 19%
- same as before but
- 3G data connection on - mobile data connection always on
- gmail push received a short email while testing
- hotmail checked mail as scheduled and downloaded 6 short emails
15 minutes later
= still 19%
Tests were started as soon as % showed the reported number.
By night, on airplane mode, it loses about 2% in 8 hours.
Can't really complain. By the way I'm still searching for a tool like WinMo BatLog. Anybody knows if it's feasable on android ?

I've been searching the market for a while but I couldn't find a tool that shows the power drain in Amps
Brightness
Airplane mode - Completely white screen
* Full brightness:
started at 17%
after 2 minutes = 16%
(brief pause to check, then back on white screen)
after 1 more minute = still 16%
(brief pause to check)
after 1 more minute = 15%
(brief pause to check)
after 1 more minute = 15%
Lost about 2.5% in 5 minutes
* Minimum brightness:
started at 13% (didn't wait for full step, probably was already close to 12%)
after 2 minutes = 12%
(brief pause to check, then back on white screen)
after 1 more minute = still 12%
(brief pause to check)
after 1 more minute = still 12%
(brief pause to check)
after 1 more minute = 11%
Lost about 1.5% in 5 minutes
(kept going with low brightness)
after two more minutes = still 11%
after one more minute = still 11%
after one more minute = still 11%
after one more minute = still 11%
Apparently lost less than 1% in 5 minutes
Probably the % is not very accurate here anyway, or maybe at the beginning of low brightness test was still hot from the previous high brightness one.
after one more minute = 10%
time to plug it in, I'd say...

I have one battery at 3742 mV, however it's at 13% and charging.
The other battery, which is almost full and not charging, shows 4153 mV.
Don't know if it's affected by charging state.

Yep, the more juice you put in the battery the higher the voltage. So a more fully charged battery will have a higher voltage than a lower charged battery.
It goes from like 3.3v to 4.2v.

Erm, yes I've explained myself not very well... I meant that I didn't know if the fact that one was charging and the other not could impact the reading. I wanted to provide the approximate range of usage, since, if I'm not mistaken, the phone turns off when it reads 3.3v ?
EDIT: also on the same note, I think if I remember correctly, I've read that the % read is sometimes 'skewed' depending on how full the battery is. Like 1% battery at 100% lasts (for example) longer than at 50%. Am I awfully mistaken ?
Yeah, shutdown is usually around 3.2 or 3.3. It depends on the manufacturer. I think the batteries get damaged below 3.0v. Protection usually kicks in around 2.7v - 3.0v.
Not 100% sure, because I always mix up LiPo's and Li-Ion batteries
While charging the voltage will be a bit higher, and when you unplug it will go down a little bit.

Yeah indeed. The voltage drops much faster when 100% charged than 60%-70%. Also the reason why there seem to be so many issues with the wrong percentages shown .

Right, so it's pointless to compare battery drain % at full level and at 1/4, for example. I've also read somewhere that battery temperature influences the reading, as well as reducing the efficiency of the battery itself.

If you really want ill get back and do it with the *#*#4636#*#* and give you 4 digit number from there
Wifi streaming + screen on
Tested music streaming with xiia
* first run with WiFi
- most stuff off, same as previous tests
- music channel was accujazz
- music through the speaker, half volume
- WiFi on
- Airplane mode on
- Screen on (forgot the timeout off)
Battery went from 92% to 88% in 15 minutes (4%)
* second run with 3G
- same as above
- no airplane mode
- 3G in place of WiFi
Battery went from 68% to 62% in 15 minutes (6%)
I've repeated the test and still it seemed that 3G consumed a bit more battery than WiFi (5% vs 4%), but this might be also due to the fact that the first test had no mobile connection on.

Do I feel stupid now not having ever used that as a reference for testing
Hey guys,
It would be really nice if people start posting the battery life of their defy on CM7 any build.
Pls mention the build detail and how much do you use.
let me start.
i am getting around 2 days 10-15 hrs on a single charge..
i am using cm7 RC1v2
i listen to music for around 4 hrs, i msg frequently, i take pics,only 2G, wifi for an hour, no gps, no mobile data.
Lets try to keep this thread alive to help ppl who are trying CM7 and wants to know how much they should expect battery life.
Thank you
I m having the latest build july 1 and it charges only till 95............
2g is 6hrs
cm7 beta 6
around 30hs
2h listening to music
1.5h talking
30m gaming
30m web surfing
auto-brightness enabled
wifi/3g constantly on, wifi never sleeps
undervolted:
800/45, 600/30, 300/18
up threshold: 90%
vsel1 when screen is off
vsel2 when battery <20%
wow...that alot of info...thanks..really appreciated..
cmon guys...70+ views but only 2 replies??
I've noticed that if I am busy and I don't have time to play to much with Defy (using it mostly for his basic function = mobile phone) the battery can least over 4 days with moderate use (talk time around 40 minutes). I generally keep it on 2G network mode as the 3G coverage on my current carrier is not so god and I use the internet/data connection on Defy only on demand. The screenshot below was taken on CM7 beta 6.
1 hour usage can drain as much battery as 20 hours standby. So "battery life" can hardly be comparable even with slight difference in usage pattern. Maybe how long 1% battery can last on average is more comparable.
In my case 1% battery can standby 1~2 hours, or use (call, video, game...) 3~7 minutes. I was actually recording battery level/time with pen and paper but not by impression. And I don't notice big differences among roms, including orange, finland, noric, hk/tw, or cm7.
And I noticed that after using the 720p recording patch to record video (in other stock roms, not cm7), battery would be drained at 4% every hour standby.
3 hrs of GPS tracking, screen off, 3G always on:
100% to 70%
Hi !
With rooted froyo (the official one from Orange France), SetvSel to undervolt the proc (vsel3 : 52V @ 1000 MHz, lowering by 2V the others vsel), i could go for more than 26hrs with one charge.
Now with cm7 nightly from 01/06 n°0114 (which by the way works like a charm and was really easy to install even for a noob like me), no undervolting at all, 9hrs drained 35% of the battery (with a more intense use I must recognize), which leads to a little less than 26hrs.
I will try to undervolt it, but I definitely think I will get a better battery saving with cm7 !
It's terrible to see that with some little tweaks, cm7 moto defy beats the stock one.
I consider that I paid moto enough that they can provide these tweaks by default in their product, it doesnt cost much time (in my case less than an hour) and it benefits a lot.

In my case 1% battery can standby 1~2 hours, or use (call, video, game...) 3~7 minutes. I was actually recording battery level/time with pen and paper but not by impression. And I don't notice big differences among roms, including orange, finland, noric, hk/tw, or cm7.
And I noticed that after using the 720p recording patch to record video (in other stock roms, not cm7), battery would be drained at 4% every hour standby.

wipe battery stats after flashing a ROM..read few post above to know how to do it..
turnoff wifi,3G,gps,bluetooth and mobile data when u r not using..these consume battery alot!
or else use apps like juicedefender or green battery app to do it automatically..
reduce screen brightness or keep it in auto brightness mode..it will save alot of battery
task killers might help..some people says..but i think it consumes more battery then it gives
avoid using live wallpaper..i know it looks gr8..but its not gud for ur battery
try these and report here..
All the best
my battery uses is not normal
help!!!
the display use too much
sorry for it is chinese version
hope all can identify the icons

Hi... I have an Xplay rooted on 2.3.4 and removed light bloatware, but still my battery drains fast...
I must charge phone every day and I dont use a lot of heavy gamming... I only play in bed at night and normaly to drain the rest of the battery before charging.
I almost never use 3G, but have always wifi turned on...
So, resuming, my battery only lasts about 12h-14h per day...
As you can see, in the attachemt I have 2 times the same thing (portuguese language, but will translate):
- Inactividade do telefone 28% (Inactivity off phone)*
- Wi-Fi 21%
- Telefone inactivo 15% (Phone inactivity)*
* This 2 things arent the same?
I have a few questions:
1º - I have read about people who can have phone about 2 or 3 days, others with 20h or more. What is the most accurate and normal on this phone?
2º - If wi-fi always turned on, will drain battery?
3º - Why most off % is used when phone is inactivity?
Sometimes the phone dont loose battery when "sleeping" (it take 2h to loose 1%), but other times, when sleeping, battery drains 10% or more in one hour. I have read about a bug in Android OS that drains battery when phone sleeping. Does this bug applys in ALL ANDROID phones, or only Samsung? Read it on here: http://forum.xda-developers.com/showthread.php?t=1290020
If I charge phone every day will get battery "addicted"?
One thing im shure: the 3 first itens on the screenshots are draining my battery whitout a reason (i can understand wi-fi, but can't understand why 2 things saying phone inactivity, uses 43% of battery)
In that screenshot, battery is on 60%, so I losted 40% in 6hours with 20 minutes of gaming... and on those 6 hours, almost half, phone was "sleeping", again, it shouldnt drain battery when sleeping.
Thanks in advance for your help
What's shown as draining your battery the most is your phone's cell standby (your 3G & 2G network, or 4G if you have it). The third on the list describes your phone when it's not in use (screen off). Don't worry about that one, a higher % only means your phone is often in standby.
Having Wi-Fi on will often use more battery than using your phone's own network. To save even more battery, turn off 3G connectivity when you're not using it (you will still receive calls, just no internet, but you use Wi-Fi anyway).
Charging your phone every day is perfectly fine, just make sure you unplug it once it hits 100%. If you leave it plugged in while it's fully charged, it gets bad for the battery after a while.
That article about the battery drain in standby is likely just for Samsung devices. What is likely draining your battery are apps and services that run in the background and use the internet while in standby.

95% of the time, 3G connection is OFF. I use Wi-fi connections, because I have many hotspots for it...
I don't have many APPs and the ones that I have installed (non-stock apps), dont run in background.
Today, I turned off wi-fi, and only turned on when need, and for more than 2 hours, only losted 1% of battery (have takken photos, and made phone calls only).
After this I used wi-fi for 20 minutes, and losted 8% off battery. So I think, Wi-fi is the problem. Please correct me if im wrong:
- If I have wi-fi always on, phone is always searching for wi-fi connections, even when sleeping, so battery drains much faster.
As you can see on the screenshot, with no wi-fi, for a little bit more than 2hours, only 1% of battery losted
Well you answered your question. Wifi is the problem. If it searches for wifi networks all of the time the battery will surely drain.
Definitely Wifi. It absolutely murders my battery when I forget to turn it off when I'm not using it.
Yes... for shure... its crazy like hell... lol... half an hour playing... half an hour surfing (youtube for my son... i put videos for him, once in a while)... and wi-fi drained more battery than gamming (FIFA 2010, Angry Birds, Spider-Man... also my son played)... funny thing, he has 20 months old, and love Xplay, more than me...
So... the hole day, I kept wi-fi turned off, and only turn it on, when needed... more than 12h latter, still have 62% off battery... and for the first time, will not charge this night...
Was so simple, as turning wi-fi off... check the screens...
Thanks all that helped
Hello
I have new Samsung Galaxy S4 I9195, and everything will be ok, if the battery life will live more then a day. First few days the battery life was around 2days. Yesterday i plug off from charger (i only charge when it drop abut 15-10% to 100%). I go sleep with about 70% battery, and in the morrning what was my suprise when the battery was below 45%. What the **** i mean.
And i looking for the suff about the cell standy and i dont know what to do.
I find something like that:
http://forum.xda-developers.com/showthread.php?t=1763683
http://forum.xda-developers.com/showthread.php?t=1732722
I use only 2G and in home i have always wifi turn on. As you can see in 15min phone eat 2% from battery when i write this post.
Phone is 90% time in one place where signal power is-73dBm 20asu
Whats the problem ?
I find this normal, 15 min - 2% (depends on what you are doing) i suggest you to turn your phone off when you are sleeping.
if i use chrome for like 5 min it drains 1/2 %
candy crush 10 mins drops 3/4 %
i have 17/18 applications so, it also depends on how many apps you have.
more apps is more battery use
so dont worry
Edit)
and 2% drain for posting this?
your lucky bro, my phone will drain probably 3/4 % (not sure)
@lgorek, to have some hints, read all this thread :
http://forum.xda-developers.com/showthread.php?t=2380723&highlight=drain
It could be a bug in the stock ROM. arco68 seems to have fixed it in his custom stock kernel :

For 99% there is problem for now i test it and search of the bug.
I notice that when i restart phone when is charging or after charge the battery life is at normal drop, BUT when battery drop to 10% i plug the charger and it reach 100%. Something is not working fine becouse the cell standaby power drain more battery.
I give more info in few day i will have more photos and you can see it.
dsavard i will check it, but first i test like i write up.
