Battery re-calibration??

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.

Extreme Battery Drain Issue

When I woke up this morning, I turned off my phone and after it booted up I unplugged it, because I wanted to get a realistic idea of it's battery life (it's been fluctuation on me). It was at 100% I'm reading at 19% now, I have an Up time of 3:12:00 and an Awake time of 2:44:16 (I have been using it pretty constantly, so the awake time doesn't worry me too much). This is obviously ridiculous, this could possibly die in less than 3 & 1/2 to 4 hours. Battery use is: Android System: 58%, Display: 17%, Cell standby: 14%, Everlands Lite: 6%, Phone idle: 3%, android.process.acore: 2%. I just downloaded Everlands today and played it a lot, but with that low of a percent it can't possibly be an issue. I'm running Damage Control v3.2, and I'll post the DConfig in the next post.

Please, any explanation for why my battery drain has suddenly jumped up so much would be greatly appreciated!

did your battery suddenly start dying quick? mine will last all day ONLY if i leave it alone all day, no calls or anything. If I use it minimally i get about half a day and if I have heavy usage on it then I get about 4 hours or so.

Prior Battery Life
I was able to go about 17 hours off the charger once without holding back on my usage at all, and that wasn't a huge outlier. Seriously, I know I've been able to get at LEAST 12 hours out of it streaming Pandora for an hour plus lots of texting, twitter, facebook, web browsing, and even moderate GPS usage.
I think other battery threads would be more useful if they included Awake time more often, because obviously I am not having a problem with it not going to sleep (since I was actually using the thing almost the entire time I had it off the charger).

You may actually have a bad battery. Mine gets unplugged at 6am, has a 30 min charge at 8pm on my way home in the car, then plugged in at 11:30 or 12 with 40% left.
The only thing I have done is kill most of the widgets, use a static background and that is about it.

you might have a bad battery, or maybe it was just something for that time. if it keeps happening, go back to sprint and they'll probably give you another battery or even phone (assuming they have them in stock)

Battery Defect?
I tried the method that one user supposedly learned from HTC ( I can't post a link but it's titled "Official response from HTC RE: How to double battery Life (WORKS!) + 2nd Reply" ), and I'm not sure I've gotten the same battery life out of it since that happened. I just got it charged back up to 100% now, I'm going to try upgrading to Damage Control v3.2.2.1 and I'll throw it into the Power Save mode in the DConfig, then see how long it lasts.

Post your Battery life of your defy on CM7

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.

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!!!

battary life drains so bad(version1.28)

I charged my HTC ONE X to 100%, took it out of the charger and I have now been 1h 37m 46s on battery, and it ALREADY has drained to 70% !!!
what my phone uses or so it says :
screen 78%
cell standby 6%
android OS 5%
android system 4%
phone idle 4%
whatsapp 3%
what does it mean 78% screen? that my screen is the big killer for my drain? because that would make non sense since I have not had it on that much..and still.....30% in 1.3hours? that's just insanely bad!
stock rom from Holland btw...didn't change a single thing to my phone since I do not know how....
any input on why it drains so rapidly?
thanks!
I would post a screenshot but I don't have ''root'' access'' or something lol sorry!

you are ok bro. for me it drained 17% with 15 minutes screen on time.
this is one big lol.
i am struggling to get 7 hours battery life

If you don't mind the effects on warranty, there are some system mods things that can be done to improve battery life...
Otherwise try turning off extra wireless services, and lowering the brightness on your screen.

I was getting 8-9 hours outa my battery, since rooted and flashed leedroid's rom and I got 26 hours with 30% to go....
what a difference.....

Basically in android, especially LCD screens, you can expect under 3 hours of continual screen use in daily activities. Often way under.
I've gone through a Motorola Milestone, Samsung Galaxy S and Nexus S, HTC Sensation and now One X. None of them broke the three hour mark for screen on time.
Standby and other use, sure, you can push a day or so but the screen is the major killer. Even with 1900mAh after-market batteries for the Sensation I was just about pushing 2.x hours. Screen usually on auto, but often inside buildings.
Counter to what may seem obvious is that if you have WiFi available - use it. It uses less power than the data connection on cellular networks and can improve standby time by a fair bit. Assuming you use push notifications and the like.

is rooting hard? i searched it on the internet but the only thing i found was some half-assed english site trying to explain what to do...couldn't follow it, and also it didn't work :/
I don't know all the terms etc they use so that makes it quite a fair bit harder for me!

Two Questions:
- What are your Brightness settings?
(Settings - Display & gestures - Brightness)
- Do you have Wifi/3G constantly on?
(Settings - Wireless & networks: is Wi-Fi and/or Mobile network: ON?)
How to improve Battery drain:
- Go to: Settings - Display & gestures - Brightness:
and untick: Automatic brightness
with your finger slide the brightness level to much lower than it is now (I have it at only 1/4)
confirm with: OK
- Whenever you do not need to be online (internet), make sure to switch off Wi-Fi and Mobile network
- Switch off notifications for e.g. Facebook, Twitter, Email (you need to open each app and in the Menu have to untick notifications)
From personal experience, I can tell you that having internet on constantly aka WhatsApp sending notifications for each chat message, Facebook and Email sending notifications, ... costs you a lot of battery
Brightness at full level also drains battery badly.
- Following above-mentioned tips, you will get a standby time on the HTC One X of up to 2 full days.
Hope I could help a bit.

You need to get on leedroid Currently on 71% battery also, but slight difference in how i got there:
16hrs standby
half hour screen on (auto brightness)
5 mins calls,
3g/wifi/locations always on.
Very light usage day for me, but it's very different results to yours

edited for clarity/typos

who would you have your phone on standby for 16hours....I used it more than half an hour a day (half hour screen on as you said) so that says nothing for me lol
and my screen has low brightness but that doesn't really seem to effect it THAT much, but yesn i do have 3d on constantly aswel as fb whatsapp etc...but I do need to be in contact with people so I guess there nothing to fix :/ except maybe a ligh rom but i have no idea how that works haha, might search youtube

I have the same problem but i'm actually using the phone.
As a heavy user (and i mean heavy user) i've yet to get more than 3 hours on screen time with this. once i used it for only 2hours 20 mins and the battery was dead. I'm rooted running leedroid and the battery life is very bad for onscreen time.
Anyone else getting these figures.

hi guys..
i am on stock rom updated to latest but having problems with my battery
take a look at the screenshot. i currently have 30% battery.
as you can see from almost 11 hours of my latest charge 9hours and 20 mins
my phone was at deep sleep.(only 1hour and 40 mins of light usage)
when its locked it shows excelent battery (1% per hour) but after an hour passes and even if i just unlock it and browse a bit my phone ,i lose 5-6% .
my phone is 4days old only.
maybe the problem is just temporary?
thnx in advance for any help.

I'm using an App called 'Screen Adjuster', in which you can set the screen brightness (say 50%), and then auto adjust brightness within the selected range (50% range).
You can adjust the brightness anytime, I found it is very handy because the original auto brightness is simply too bright.
One drawback is that you can click to install 3rd party apk with this App running, don't know why, but just for your reference.

This is what i get.
With surfing a little bit gaming and chatting.

High battery drainage overnight with only 2G off

Got a new battery, original samsung, as I tought my 18-month old one was a little wearing out.
Still, overnight, with only 2G on (so no 3G, no wifi, no sync) I get a 1% drainage per hour, as you can see from the attached pictures:
- in 9h 11m the phone is in deep sleep for 98% of the time still with a discharge rate of 1% per hour
- 100% of time with no signal and no data connection
Kernel and partial wakelock also do not seem a problem, but maybe I don't know how to read this informastion.
Even the cpu is in deep sleep for 98% of the time.
Really do not know if this is normal or not...
