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.

What is everyone's cell standby battery usage, percentage wise?
Mine is 41%, which seems a bit much.
My battery is down to about 30% in about 6 hours (most of which was in standby).
I'm trying new roms and kernels, so I'm trying to determine whether or not that's the problem.
Today mine is around 34% and I have seen it as high as 41%..After almost 13hrs still at around 65% battery but I've been light on my phone today.
I've been incredibly light on my phone today.
When in some of my classes, I have horrible/no service. I'm thinking that has a lot to do with it.
Are some ROMs or kernels more heavy on the battery when not in service than others?
With my stock rom and kernel, my battery didn't last long, but it was much better than this.
Im usually about 41% also seen as high as 43% but only once....as long as your time without signal is low I don't think its that big of deal..but, if they is a way to lower it without goin into airplane mode would that help battery life?
Well if you guys' cell standby usage is as high as mine, then I guess that it isn't the problem.
I was just asking because it seems like I remember hearing that some phones increase Tx power when they don't have service in an attempt to get a signal.
Mine cycled through 1 bar, roaming and no service for about 50 minutes while in class today.
Maybe I'll just try different ROMs and kernels and find a combination that works for me.
~7 hours of use isn't cutting it since I was getting significantly more time with the stock ROM.
Thanks, guys.

A typical battery usage in standby with only 3G on (mobile data always on = off, gtalk = signed off) should be between 1-2%. In 6 hours of standby, you should not have lost more than 6-12% of battery charge. A full charge should be sufficient for about 3-4 days of standby.

He is not talking about the same thing we are.......he is talking about actual battery usage via battery icon, not the settings, about phone, battery, battery use screen.
I get approx the same battery use few % an hour with phone standby @ 43% of total battery use as long as I have a good signal and not using the phone
Two different things dont get confused.....
JuiceDefender has done the trick. I'm at about 45% battery remaining 8 hours and 2 minutes after being unplugged with 35% of the damage attributed to cell standby.
The only caveat is that Gmail and Google Voice don't push instantly. Of course 15 minute intervals are enough for my email, and a simple text upon receipt by Google Voice lets me know exactly when I get a voicemail.
Thanks all for your responses.
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 everyone! I just switched to my first Android device and am truly enjoying the experience. I can't believe I was using an iPhone for so long. I finished draining my battery for the first time and recharged it and am draining it again. My phone indicates that the screen is consuming around 66-70% of the battery drainage while everything else is quite low such as the Android OS taking up about 12%. Is this typical and does it improve over time? Thank you for your help.
this is normal but seems like that is pretty heavy use. if your phone was barely used then that is not normal.
I am going to further diagnose this. I have my brightness set to auto. I wasn't really using the phone that much. I flashed it to the yakju build and it is running 4.0.2. Is there anything I should do to test the phone?
what is your screen on time
I'm looking at
9h 56m on bettery
Android OS 33%
Phone Idle 30%
Cell Standby 22%
Screen 9% (on time 9m)
Wifi 5%
Google Services 2%
This is after the phone being nearly untouched most of the day, no calls or texts and nothing being done but checking my email once not too long ago. It's on Auto-brightness which sucks because it appears to be on the darkest setting but without that my battery seems to go from full charge to 50% in 1-2hours with moderate usage (Browsing the web, Checking email, Browsing Market, few phone calls and texts) and it sucks that I feel like I cant play with the phone because it'll be dead when I need it and without Auto-brightness the battery dies even quicker.
Almost feel like I need to be tethered to the charger.

you either have really bad signal and/or 4g and/or a process keeping the phone awake, in your case the high cell standby time suggests the first two
This seems common for the lte version. The gsm version gets very good battery life especially idle drain. Turn off lte is your best option.

Assuming you have the screen on a lot then yes. Those big beautiful screens are hard on a battery.
If you're on the LTE version using 3G only you will get around 3 hours screen on time MAX.
GSM version you will probably get 3-4 hours screen on time per charge.
Hello all,
I bought a new Z play to replace my ageing phone, and I have mixed feelings about the battery life. The phone has received universal praise for its battery life, and while some of it is true in my case, I can't seem to get those high SoT numbers that everyone brags about.
It's very difficult for me to break the 6h SoT barrier, and I consider myself a light user: whatsapp, browsing, some reddit, and the occasional music (through headphones). I don't play any games, or perform heavy tasks. Also the phone is connected to WiFi 85% of the time, get decent signal, and the screen is set on auto-brightness.
Running latest version of the stock rom, and I performed factory reset + wiped cache + reset network settings countless times as per suggestions.
Attached some stats for 50% that I just took.
Is there something I'm missing?
Take it with a grain of salt, just because people brag about numbers does not mean they are real or obtainable by everyone. Battery life will vary for every user and phone. The time you have is in the acceptable range and I would not worry.
Yes, even I have never achieved the 8-9+ hrs of SOT that's I've seen in some threads. Based on my usage I get a minimum of 6.5hr SOT with the phone lasting a good 25-27 hours before I have to plug it back in.
Since the phone is new it might take a few cycles for the battery to truly show its stamina.
Those answer are definitely right. It all varies on the users. . Also please makes sure you have bluetooth and wifi scanning off. (Location> Scanning > Bluetooth & Wifi Scanning) Another factor is apps. Get rid of facebook and facebook messenger. Apps that use GCM eat battery like a range rover eats gas. I've hit 8--10 hr of SOT before. Let your phone get use to your daily activities. I believe it'll optimize itself over time.
It's normal.
I was also getting earlier 5-6 hrs SOT(When the device was new) but not I'm getting 8-9 hrs SOT.
So as your phone is new it might take few cycles for the battery to show its full stamina!
Cheers!!
Thanks for the replies and for putting my mind at ease.
Bluetooth and wifi scanning are off (forgot to mention that).
Anyway, I understand. Those insane SoT of 10+ are best case scenarios with careful use of the device. Still happy with my current capacity (anything which lasts until the next morning is great).
And yep, the phone manual (who reads those anymore), did mention the battery taking a few cycles before reaching its capacity.
Now, for a different issue. If I'd like to disable turbocharging/quickcharging my phone, would a USB C to A cable coupled with any charger (including the quickcharging ones) do the trick? Based on my understanding, the cable limits the chargining power, so any regular (quality) C to A cable should restore normal charging speeds even when using a fast charging charger. In case you're wondering why I'd like to do that, it's because the phone gets way too hot for my liking when using the Moto turbocharger and I'd like to reserve that for when necessary.
Well, guyz do have a point.
The screenshots are showing you have almost 3hrs SoT after day and a half. This is normal.
Those >10 hrs of SoT aren't achieved with careful usage. Coming from my experience, I got 10.5 hrs SoT with 10% battery left, BUT, in one day. My Moto can last up to 3 day with one charge, but in those 3 days I'll have maybe 4hrs SoT. So, in average, my Moto lasts up to 2 days with 6/7hrs SoT (I mostly use FB, Messenger, WhatsApp, Viber, YT, Instagram, stock 6.0.1). It simply depends how you use it. That big, almost 11hrs SoT, I could only achieve on weekends, coz otherwise I don't have the time to stare in my phone so much.
On that other thing, Moto does get pretty hot while charging. And you're right, the cable does limit the charging power so it will probably work.
I was one of those users getting 10h SoT early on. But I was doing that inside a 24h usage window. Your 50% stats have you stretched out to like almost 3 days off charger. Idle time vs. screen on time is ALWAYS a trade-off.
I look at battery drain in terms of drain rate at idle, and drain rate with screen on. Early on I was seeing 6% drain per hour of screen on, and 1-1.5% per hour screen off. So basically 5 hours of idle time costs you 1 hour screen on. Those were my numbers on the original MM build. My battery life has gotten worse with every software update. I have NOT done a factory reset, mostly because I don't want the hassle and I still get a day off normal use with plenty of battery to spare. But I usually see 18h off charger and 3-4h SoT in a normal day, and that leaves me at 40-50% when I plug in.
Looking at your stats, if screen on costs you 6% per hour, you have 17% worth of screen on drain. That leaves 33% idle drain over 38 hours, or sightly less than 1% per hour idle. Seems pretty darn good to me.
Your cell signal is definitely not helping your battery life. Switch to 2g when on wifi, your signal bar should be full and it'll probably help your battery life.
Enjoy the fact that this phone lets you keep BT/WiFi scanning/Facebook/etc. on without having to worry whether or not you're going to make it a full day. I use all that stuff, have multiple live widgets updating, brightness at least half way, T-Mobile Digits running, and still make it a full day. Additionally, it's great to know that if you do have to make it 2-3 days with minimal usage because you don't have a charger handy, you can. However, I'm willing to bet that 99% of users are able to charge their phone daily. To those users, I say enjoy all the features and don't worry about it.
Really depends on the screen brightness...I can hit those number with my screen brightness turned down a good bit...probably around 30 percent and auto sync off...if i have brightness anywhere above 60 percent then battery life drops a good amount...still well enough to get me through a 12 hour work day but there is a difference
