[HALF-SOLVED?] Battery issue fix needed

hi there!
as mentionend by users in other threads, it seems that a high number of raphs have a draining battery issue - compareable to the bug in our kaisers about a year ago: batterystatus measures around 70/80 mA in sleepmode with all programs and tf3d closed - on a kaiser with custom rom was around 4mA (!!).
So please, dear chefs: Try to figure out how we can fix this one
Check out some kind of solution / a way to improve your battery uptime: http://forum.xda-developers.com/showpost.php?p=2770702&postcount=25

Update: Battery was sucked empty from 90% within 3-4 hours in the night (!!). No running programs. In the chart you can see the difference between loading with the 220V plug and the USB-cable (last part of the chart). Sometimes it looks as the device sucks more power than the usb loader can deliver -> battery will get empty even when plugged into the computer the whole day.
Looks as we really need a solution thus waiting for htc or cellproviders is useless :-(

Can you check this? Start->Settings->System->Power. Make sure that the "When device is turned on, do not charge the battery when connected to the PC" is unchecked.

Of course it is unchecked - but thanks for the hint!
I still need to get over the shock that it took just 3-4h to ground the battery in standby without running programs oO

for me it helped a lot to improve battery life to set the setting 18.4 (energy saving) in diamond tweak...

I need to compare the tweaks but i enabled energysaving options with Advanced Config... - but I will give diamond tweak a try and even do a hardreset in order exclude 3rd party software for the power consumption...
ill report soon!

im having battery issues, too.
sometimes the phone gets unresponsive, really hot and battery drops 30-40% in ~1h minutes - without being used.
i love my touch pro, but ive got so many problems (crashes, hang ups, battery, broken screen thing, grey display with stripes, the list goes on and on...) that im considering to return it

So... small update of my findings:
My Raph(s):
R 1.02.25.19
G 52.23.25.1.7U
D 1.69.00.00
The power consumption usually never falls below 75mA. It goes up to usually 240mA, 700mA yes sometimes 1100mA. (Again: in standby!)
Comparison: on the kaiser it was around 4-12mA with Teijaks V5.
The following changes WONT affect this problem:
o disabling TF3D
o switching to GSM/GPRS only
o switching off persistent internet connection (e.g. exchange server) (!!!)
o kicking ALL not absolutely necessary backgroud processes step by step and measure between
Naively i thought that someone may be interested in that behaviour and called my provider t-mobile... ok, bad idea as they seem to have none knowledge about that devices at all.
But at least I got a number of their hardware-supporter / servicemen "Kapsch" who couldnt help me either but where kindly enough to pass me a number of HTC here in Europe.
The nice lady with basic knowledge about the devices as well as the language we were talking in came to the conclusion that the only solution would be to send the devices in via my provider.
Well, so they believe that exactly theese 3 raphaels here are the only ones to suffer from that power drain (hardresettet, blank installation, bla bla like above)... and sending them in (what means: dont see them again for a month or so and get them back in the same condition) would be THE solution.
Somehow i am pissed that i already sold the kaisers and wonder how it will be next week on a businesstravel with an unpowered TomTom outside the car and a phone which drains in a few hours in standby
(Sorry for whining around...)

Completely agree with some of your figures, however the highest i have ever seen is around 550mA. Usually after no data transfer i get it to drop to between 89 ~ 110mA. How are you measuring standby current? When in standby, how can the software measure the current? I only ask as like you, the lowest i have seen for current is 82mA, however this figure would give a max standbytime of around 16 hours. I have found that the TP in standby performs the same if not better then my old kaiser which, like you measured around 4mA in standby. From what i have seen, i can not measure a true standby current like i could on the kaiser.

I measured with CommMgrPro and batterystatus...
Measuring a "real" standby without changing the battery with an Ampere/Voltmeter is not easily possible i think... so i use CommMgrPro and accept its own usage as somekind of "Baseline".
Or - if you dont need a chart / history, i use the much smaller Batterystatus, disable TF3d to see the Homeplug and close all applications. With all apps closed i turn of the device, wait a minute or to be sure that it has gone sleeping, and wake it up. A few seconds after turning on the mW/mA measures will jump to the "standby" values due to its delay. Not 100% accurate but okay for comparison reasons...

OK, this i could do on the kaiser, but not on the touch pro. Each time i turn the phone on, i see at least 82mA, which would only give a stnadby of 16 hours - but i can achieve 3 days, so clearly this is not the standby current.

3 days.. i can only dream of that That would mean that you got around 19mA drain in standby... how do u measure?

Thats what i'm trying to say - i cant measure anything below 80mA when i turn the TP on, however it is obviously NOT the standby current as i can obtain 50mA with a dim backlight, plus get 3 days standby. When i state 3 days, thats with no usage!
I'm just trying to point out that what you think is the standby current, probably isn't and we all know that there are issues with the battery management on this phone.
Another example, i have had my phone of charge since 7am, made a couple of short calls, 5 mins of wap browsing, and its currently reporting 95%. If my standby current was 80mA, it would be down to 50% by now. However, assuming i continue to use the phone in this way, in theory i should get 160 hours, which indicates an average drain of 8mA.

I agree - of course you are right and measuring this way can - if anyhow - assist in relatively comparing two devices/ configs but not deliver absolut values of course.
With batterystatus it worked pretty well on the kaiser - and even on the raph i could see 3 or 4 times my beloved 4mA... but in 99% its around 80aH ind standby and around 300-400 in usage which seems plausible regarding my usage.
Nevertheless i had several times a "hardcore" drain where i must had (mathematically) around 400 during standby and maybe even more during worktime when plugged in via USB: It DISCHARGED what means that it used more power than USB could deliver
(usb charging settings correct)
If I dont get my callback from my provider today, then i will try an inofficial RadioRom this weekend...

In standby mode, all application should have been paused by the deviced, right? Then how can any application measure the power usage in standby mode?

some apps keep going. thats how you get messages
i can get 2days out of my phone with heavy usage

That is because the OS send out events when something happens, thus waking up the device and letting the apps run.
For SMS, sim card receive message, sim card inform OS, OS wakes device up, OS send out events, app capture the events.
For alarms, OS wakes device up when the schedule reached, then send out events or start apps depending on the alarm.
So, device must wakes up before apps can do anything.
Some apps intercept the standby button (power button) and instead of letting the device goes to standby when pressed, just turns off the display. For TP, HTC has modified something (or loaded some apps) to make sure that when you are playing the music or listening to the radio, the power button just turn off the display instead of going to standby mode. If the device goes to standby mode, the device could never play any music.
So, if the battery benchmarking app you are using is able to measure the power consumption when the device goes to standby, I doubt it. It actually just turn off the display.

I seem to have fixed or at least drastically improved my battery. I was suffering major drainage with moderate to heavy use, after about 5 hours the power would go down from 100% to 10%. I have WiFi on permanently and do a lot of emailing and texting.
I drained the battery to 0% and with the phone off (not in standby) I charged it using the AC adaptor. With it fully charged and the button light on (glows when charging, solid on when charged) I turned the phone on and first time it said 88% charged?!?! But it lasted the whole day and even had a good 30+% left at the end.
Did it again, ran loads of apps and switched everything on until 0% battery. Charged over night with the phone off. Next day it said it had 95% charge when I switched it on and again it lasted all day with quite heavy usage.
Discharged it again that night and plugged it in, today it says 100% and I'm pretty sure it will last even longer.
I've also found that after doing this, if I don't use the phone and the screen is off, I can leave it for 4 hours and the battery percentage doesn't even go down 1%.... which is a bit unbelievable but happens.
PLeased to say, now this last gripe seems to be fixed..... this is by far the best smartphone I've owned or used and on the market. Great step up from the TYTN II and iPhone (nice toy but useless for email and destructive with exchange servers).

True. Draining the battery completely really helps. I've done it about 3 times and now my device can reach 2 days of heavy use with 1 charge. When I bought it drained very fast and charge indications were way of. (1 hour charges would just increase charge level with 5-10%).
What also adds battery life ia disabling activesync in the notification queue. Use memmaid or a similar program. Go to the notification queue and disable the entry for repplog.exe with the comment "system time changed". Activesync will function normally when connected to a PC. Not sure about OTA exchange syncs though...
Hope this helped

Hi,
I've found that the Raphael battery stops charging when it gets warmer than 48 degrees Celsius. I discovered this because I am using WMWifiRouter all day at the office, and noticed that although I have the Raph connected to a 2000mA wall charger, the battery drained and device got down to 10%.
The trick is that I have to put the device in "standby" mode py pressing the power button. The screen goes off, but the device is still running. This resulted in a lower device / battery temperature, and the battery remained at 100% after 8 hours of usage with WMWifiRouter and connected to the wall charger.
I can contrast this to with my Kaiser, which didn't stop chraging the battery until about 65 degrees Celsius!!
Maybe that helps too.

my little rant about the battery life.

the battery life on the raphael is a bit.. odd. Before I had this phone, i had the Sidekick LX, which was able to last about 12-14 hours and it didnt really matter how much I used it. The data on the sidekick is on all the time, but it is Edge.
However, using the ATT Fuze (raphael variant), I am a bit happy, and yet, a bit upset at the battery life. First, if i do not have data on, the battery lasts extremely long. Its been more than 12 hours, and i am at 85%. I had minimum web browsing, made a few phone calls, and talked for about an hour. Oh and i have email updates every 2 hours. Thats pretty remarkable for a smart phone.
BUT, if i am to browse the internet, listen to internet radio, or have an instant messaging program open, the battery drains at least 10% every hour! Thats horrendous! What is the point of a 3g smart phone if i cannot really use it because the battery will die if i do?

Hmm, I have hammered my phone the past few days with texts email, phone calls, messaging and some light video usage. It lasted about 10 - 14 hours and I charged it once a night. I have been pretty pleased with it.
I leave data on all the time and it will download my RSS feeds every 2 hours pictures and all, weather will update etc so its always using something. With normal usage and the always on stuff I have had it last about 2.5 - 3 days making very short and few calls.
With the screen being on, data going and all of the other stuff it saps the battery fairly well. I wish battery tech would advance a little to make it last longer but its better than my last phone by a good amount.
Have you made any of the power saving tweaks from that thread to your phone? You should be able to squeeze some more juice out of it.

There are several Raphael power tweaks on this forum, I would find them for you but am about to go to bed and am really tired. One I remember is you can put a disconnect time on the data using diamond tweak so it disconnects from data quickly when your not using it and saves battery. Sorry for not eing fo more help.
Did you condition your battery when you got the phone? That can help with you battery life sometimes.

Battery gone wild

I have the phone for about 6 weeks and really didn't have too many problems with battery life until I bought a stereo BT headset and started using it in the last week or so. I had the battery literally drain to nothingness twice this week already in a matter of hours. And no, it wasn't off hook or on Wifi or left playing something. One time it was actually plugged in to a USB charger!
Do you use an A2DP headset or leave your BT active?

Dont get me wrong guys. I am aware the battery does drain when i do use it. Yes, i did do the most tweaking i could possibly have done to lengthen my battery life, but lets face it, streaming youtube videos through the youtube app will drain the battery 10% an hour.
The one thing that gets to me is why instant messaging programs drain the battery as fast as youtube streaming.
I did not make this thread to ask for help though, just contributing my 2 cents to my experience with the Raphael.

10% an hour??? Howd you fit a powerplant in your phone?? My battery drops to 50% in 20-30mins if I watch youtube movies. Are you watching in HQ?

well maybe more than 10% but definitely not 50% in 20 minutes lol.

My battery seems decent, I conditioned it by draining it to 1% and charging it to 100%, draining to 1% charging to 100% etc for the first few cycles. Basically I didn't charge it until it was drained. It doesn't hurt to condition, but I think it's just superstition by now, many people say modern Li-On batteries aren't supposed to have memory.

There are several threads about battery life around here already, no need to start a new one.

Again with the Battery

Is anyone that is having battery issues running Adao Task Manager and Battery Status Pro?
I just factory reset my phone and I got 24hours of batter life. About 8 standby but a good deal of texting, web, some calls and some you tube.
I installed Task Manager and Batter Status Pro last night and my battery this morning went down 15% in about 1hr.
I uninstalled these today and will post again but has anyone else seen big battery drain from these apps or does anyone that is having issues running something similar?

I have been playing with the battery for about a week now.
For me this phone runs pretty good during stand-by. I would have about 2-3% drop for a whole night (7 to 8 hrs), with Google (push), Twitter and weather syncing.
The problem is when you use it, it drops like crazy. When I read news or surf the web, it would drop 1% every 1 or 2 min.
This morning I read an ebook, with black background for about 30 min, it dropped about 3%.
So basically i think the screen, data connection, and non-black background are the ones that kill the battery.

Yea, I agree, the S-AMOLED screen in this thing is an energy hog. OLED's are supposed to be more energy efficient than typical LCD's but I'm just not seeing it. Whenever I look at battery usage stats it shows the display at 70-75% of battery usage. Thats ridiculous. I have until the 18th, but I'm quickly leaning towards returning this and just getting an iphone4. This phone is becoming more and more disappointing the longer I have it.

This morning I have been uplugged 4.75hrs and used 16% no battery monitor and no app killer. Basically done the same things I did yesterday. Some Bebbled,texting, email, phone calls .
I will update tomorrow with total hours battery life for today. Would be happy if I can replicate the 24hours I got the day before installing those apps.

I got like 45 hours of battery with moderate usage during the two days. Seems fine to me, I occasionally used system panel to monitor if anything was using high and constant CPU

This is pretty typical of a 1ghz phone My nexus would last a day of heavy usage, 2 days if i use it lightly. We need to wait for undervolted kernels to be developed xD
Also, it really helps if you disable 3G when you don't use it. This allows me to get 3-4 days of light usage out of my nexus. I haven't played with the Captivate long enough to know how much of a difference this makes on this phone though

when you guys refer to "stand by", what exactly do you mean? Just screen off/phone idle? The battery usage on my phone when I use it seems to be OK even if not amazing, but it continues to sap life from the battery when I'm using it at an alarming rate.

Standby is when the phone is idle/screen off/locked.
The display is definitely power hungry. Using the Power Control widget that comes installed definitely has helped with battery life. It will let you toggle WiFi, BT, GPS, Data Sync, and Brightness (at 3 levels). When I'm not using anyone of those, I turn it off. When I'm indoors, I'll set the brightness to the lowest level. I'm usually at my desk when I'm streaming music, so I'll have it plugged in.

Actually they are more energy efficient on black screens, But screens with a lot of white in them suck battery bad.

This is true the white screens burn the battery etc. I just wanted to let everyone know what I did to make my battery last more that 24hrs.
First, read the Wiki guide and apply some of the battery saving tips.
Second, UNINSTALL a program called "gReader" created by noinnion. This program is a huge battery hog! At least it was for me.
Hope this helps.

Well I guess I am one of the "lucky ones" Im running a live wallpaper and have not run my battery down since the 1st day. Right now Im at 40% life and at 15 Hrs 30m since unplugged. This is with checking facebook, twitter, email, phone calls, internet browsing\video watching and following the steps for the GPS fix. The only thing I have done is install ATK on the phone, besides that its all stock.
One thing I know is a huge battery drain is Time without Service. Check that stat and see if you have anytime at all without service, if so, I am pointing to that as a major drain on the battery. I know currently I have 0% Time without signal, my fiancee however is usually in the 20+% range and her battery drains like many reports I have seen here (she has an EVO).....

Yesterday I only managed 16 hours. Web, Email, A bluetooth file transfer, short bit of gaming. I have about 5% of the cell standby time (26%) without signal. My girlfriend has the Aria which is running Android 2.1 also, has all sorts of widgets, haptic feedback on and can make it at least 24 hours. I get that it has a smaller screen but it is also an LCD. Shouldn't the Super Amoled be saving our battery some display consumption.

i get about 14 hours or so moderate usage and at the end of the day, i have about 35% left at night.

If you detail the "Display" usage in the battery usage details how many minutes has your screen been on? Mine says 1hour 2mins ...this is for 8 hours of running time. My display is using 50% of the battery (which is at 68% now).

W00t W00t today I have reached a new high 2 Days 6 hours and 29 minuts with 12% battery left.....

What I have found is keeping Wifi on while I am at work and home like almost doubled my battery life. Which is great that I can use Wifi all day and not drain the battery so fast like my Fuze. Right now been off charger since 7:30am and I have 84% left. Yesterday after 9 hours I was still over 50%. For me its better than any other smartphone I have owened.
I used manual brightness, (swipe notification bar), turn off GPS/BT. black wallpaper and set Wifi to never sleep. Also the power saving mode in settings is off for other reason and doesn't affect battery.

At 18% right now and it's been off the charger for about 30 hours. I noticed yesterday that while I was connected to wifi at home (with Y5 app), it was draining faster than when I was connected to 3g. Did some tested back and forth and JuicePlotter clearly had a noticeably steeper downward slope for when wifi was connected than when it was using 3g. Weird :\

battery life

anyone feel as if their battery life sucks? I do have 4g on at all times but I didnt think it would make that big of a difference in terms of battery life.

See my post here:
http://forum.xda-developers.com/showthread.php?goto=newpost&t=839935
Try installing a monitoring app and see if your init process is hitting the CPU hard. I haven't heard from any other mt4g users with the same problem, but lots of.desirehd users have it.
I also have seen my suspend process eating 50%+ CPU when the phone is locked/screen off. Haven't found a fix for that yet though.

I'm getting a full 24 hours of heavy texting, moderate phone calls. Battery life is better than my magic... im having no issues.

Yes, I woke up this morning and my phone was already blinking and battery is on 8%. I left it overnight with more then 60%
A big problem also is that SetCpu cannot force the scale. If limit to 768 Mhz it still scale to 1024. So not I am sure that my ScreenOff profile with 245 Mhz DOESN'T WORK!
THAT'S SUX!!!

Weird I leave my phone at full overnight and its still at full when I wake up.

Try disabling the preflock that might help before I did that it wasnt scaling properly now afterwards it is.
Sent from my HTC Glacier using XDA App

I have frozen a few apps and use advanced task killer every time i start up 9a lot of apps come on at start-up).
The result is pretty good battery life. I have only gone dead when I had a few apps (like GPS navigation) running in background and forgot about them.

I'm having 0 issues with my battery. It easily beats out the battery life on the Samsung Vibrant I had.

I'm having issues too. My battery life today was 40% at 1 PM, and when I left this morning, it was full. I hardly even used the phone except to check email :/ I have brightness on auto and wifi off. Not sure what the issue is.

My battery life has been really good. A typical cycle is charge to full and disconnect power at 10:00 pm. Up at 6:00 AM, battery is still on 100%. Today my use has been moderate to heavy. It's now 2:30 PM and I have 68% left. I typically have around 30 percent left when I put in back on the charger. I'm happy with that.
Wifi, Bluetooth, GPS, etc., are kept off until I use them. I do however leave Background data and Auto-sync on all the time.

I turned on USB Debugging as recommended and my battery life is much better. Right now it hasn't been charged in 9 hours and is at 79%. I've downloaded 2 apps, updated 3 apps, sent multiple emails, light internet use, and 3-4 calls. I'm unrooted and don't use any task killers.

That's awesome. I'm going to turn on USB Debugging mode and see if I can squeeze a little more juice out of it.

I have had intermittent battery-drain issues too. On Saturday morning my battery went from 100 down to 76% in a matter of an hour or two with hardly any use. I did a restart and it seemed better. I've also gotten into the habit of restarting my phone once a day, right before I take it off the charger in the morning. I've turned off quick boot, which I read somewhere in the forums can affect battery life. It's been pretty good the last few days. I'm at 68% now off charger for 9.5 hrs with moderate amounts of wifi, web browsing, email, and 3G network usage. I'm new to android devices so I don't have much to compare that to, but it's working for my schedule.

heavy user - fully charged phone at 7am ... start using after 7:30am
check emails, fb, txt, barely to no calls.....phone will be down to about 20% at 1:30~2pm....
yes the battery is lame...but this is a known issue with HTC...the 3.8 screen drains a lot of battery also the constantly searching for HSPA+ and 3G...
I do notice when screen is off....this phone still drains battery !!! bad =(
left over night at about 65% left in the morning I got red blinking led saying phone is below 10% .... 50% gone!!!
I think restarting the phone after a full charge is a good idea....also maybe turn off quick boot?
*update* yes I found that when you have a bad signal and it's jumping between E and H ... this eats up battery
also installed Advance Task Killer (for froyo) this helps~ now from 8am my phone can last until about 4pm getting about 3~3.5hrs more life

Mine lasts all day with everything on, playing games, email, text, etc, etc.
It is great, best phone I have had. Not sure what the issue is unless it is root.

It depends where you live.
If you get a good antenna signal, your battery will last.
At my apartment signal is low, so phone is constantly between UMTS and GPRS, plus phone is trying to hold H, so that drains the battery.
My signal strength parameters:
between -101 dBm and -107 dBm (where -110dBm is the edge of the signal/loosing signal)
3 asu and 7 asu

Average battery life.

Hi everyone, I'd just like to ask what's the average battery life of the G Pro 2? I somehow feel my device drains really fast for what it's worth.
I had around 3 hours of run time and it went from 100% down to 85% with only 53mins of screen time. 2 of those 3 hours were used on 2g, text messaging only, when I got home i used facebook and wifi for about 30mins (but wifi connects as soon as i get home).
so I'd say around 15% after 3 hours of moderate usage. is this acceptable? though I'd like it to drain a little slower.
I'm currently on V20a Lollipop, rooted but stock everything. also the brightness was set to 20% the whole time.
Could anyone also help me out (like literally hold my hand) in choosing a lightweight, resource saving ROM? Kernels are a bonus but right now, it's a bit unsettling to see lollipop eat away 6gb of my already small 16gb internal storage.
My device is still 2 days old, so I'm still a bit jumpy with it xD thanks in advance!

no, thats not normal. what does the battery option say uses most battery in settings?

UPDATE:
just did another 3-hour monitor, right now I'm looking at 3h10min on battery and it dropped from 100 to 91%.
WIFI was on but I didn't use it, 50min screen on time with 15min of voice calls.
Is it just me or is Lollipop a bigger battery drain than kitkat?

BUMP
here's what i've got:

You're pretty lucky, on an average I get 3 hours of usage from my phone. Legitimately from 100%-0%. On WiFi using only WhatsApp, playing a few rounds of a game and some music. Don't get me started on when I use it for navigation.

UPDATE:
I forgot to mention in my OP that i already had Amplify and Greenify and still had those kinds of stats.
Now I installed DS battery saver to drain the least amount of battery when I'm not using the phone, and so far it is GREAT.
Before I left for school (around 12:30pm local time) I was able to charge it to around 85% and as of writing (1:27am) it's sitting at 33% with 2hrs of screen on time. Note that those 2 hours I used for gaming, youtube, app downloading, and web browsing on wifi; I guess it's also important to note that I play really heavy 3D games (Maersk's quest for oil for instance).
Considering the load i placed on it for those 2 hours, I'd say battery life improved quite a bit, though not amazing, still a lot better than before.
When screen is off, it drains less than 1% an hour. I went to sleep 3:30am with 100% charge, woke up 10:30am with 96%, in 7 hrs i lost only 4% while the screen was off (compared to around 10% for the same amount of time before DS Battery Saver)
I encourage other LG GP2 users to try it out. Root your device to be able to use the "tune cpu" option.

What rom are you using? i had a problem charging my Gpro2, it takes 4-6hours to fully charge.
i don't know if its a hardware problem or kernel/rom..
I'm using LP rom and rooted, i also use amplify, greenify and DS battery saver. i'll get back after after a few test this week, i'll check my cable, adapter then replace my battery if necessary

Using stock LP rom V20a but rooted. Are you using the charger and cable that came with the device? I believe it was rated 1.8A. I tried 3 setups since it was weird because it originally took me 3hrs to fully charge:
1.) New charger + cable (the ones that came with the phone)
2.) My old LG Optimus G's charger + new cable
3.) Optimus G's cable + new charger
I tried these setups out on the same outlet and the new charger+cable charged faster, but it was still around 2hrs or so. So I tried it on another outlet, one that we (my dad and I) attached, and voila, around 1hr 30mins to charge while on and even less that when the device is off; note those numbers are for 0~100%
We're just living in a rented house and some of the outlets are pretty old, and I bet delivers low current (possibly due to small wires) while the new outlets we attached used high-gauge wiring.
If you're charging slow with the charger and cable that came with the phone, try to charge at another outlet that uses high gauge wiring.
