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.

Not sure has this been raised before but i searched and couldnt find any results so here it is
I normally can use my Atom exec for around 2-3 days per charge (stand by mode most of the time)
Yesterday I upgraded to the latest ROM. And installed new Pocket Plus Application and 2-3 other new softwares. After that, I only can use the phone for nearly a day per charge. (and i got nothing running on the background)
So im not sure that it is the ROM update (not likely) or the Pocket Plus theme software (most likely) or 2-3 other software that i just installed. I'll figure this out and let you know if i can confirm it. Just wanna know has anyone notice this problem? Might not only for the Atom or Atom exec?
And of course for those just bought an Atom or Atom Exec, the battery drains so fast might not a problem from the battery itself so don't rush out and get the new battery just yet (of course you can )
I have the similar problem

Found this posting of Jwright in on of the foura. It worked for me:
Everyone,
Just to let you all know...
Rechargeable batteries are prone to what is referred to as the "memory effect". What this means is that if a battery is repeatedly only partially discharged before recharging, the battery "forgets" that it has the capacity to further discharge all the way down. To illustrate: If you, on a regular basis, fully charge your battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of its extra 50% capacity which has remained unused. The battery will remain functional, but only at 50% of its original capacity.
The way to avoid the "memory effect" is to fully cycle (fully charge and then fully discharge) the battery at least once every two to three months. Simply leaving the device in the ON position and letting it run can discharge batteries completely. This will help insure your battery remains healthy. Once discharged, recharge the battery completely according to the manufacturer's instructions.
How I restored my HTC Universal battery
1. Fully charge the device with the "wall charger" not USB.
2. Put device into bootloader mode (backlight+power+reset) and run until device goes dead.
3. Charge the device completely with the “wall charger” not USB again.
4. Set screen brightness to MAX and turn off ALL power saving features.
5. Unplug the device from charger and run until completely dead again.
6. Repeat step 3, then restore custom screen brightness and power saving features.
7. Finished.
Some will say that this only applies to NiCad and NiMH batteries and that Li-Ion is exempt, but THIS IS NOT TRUE. Li-Ion batteries do suffer the memory effect! (Especially cheap batteries)
Just thought I would try and help....
be careful doing that, I've read about the wizard not charging after being left on until power failure
Most of my manuals say to plug the device in where ever possible (ie not totaly discharge). I have had a lot of device and the best advice i can give for improving overall battery life is to turn it off when you seep if you can, and if you get a lot of messages have a short time for the backlight to go off.
Also.. different versions of os seem to behave differently with regard to today screen messages. A today screen item is supposed to get a message from the os every 2 seconds while the today screen is visible (and non when its not). I have found that my dopod 838 pro sends these messages to the items regardless of whether the today screen is visible or not (under some circumstances). If something similar is happening to you the today pluggins could be doing a lot more than intended and draining the battery. I have an atom and this dose not happen on it, it could be the rom upgrade in combination with the pluggins.
Maybe this depends on the batterys but mine was having that problem of going dead at higher and higher % it started at 10 than 30 then 50 and up to 70 I think.
I've tested all the solutions in the wiki (yes the freezer too ) but with no improvements, then I did the opposite, instead of draining the battery fast I drained the battery slowly and when the Universal shuted off I pluged it to the electricity until it boots ok and the cpu returned to 0/1%, then take it from electric power again and wait until it goes dead again and did this over and over again until I reached the minimum battery of 9% i think. Great improvement since I was already looking for battery replacements... Then I charged it over night.
Conclusion I have the Universal alive for 3 consecutive days (and nights) now at 52% waiting to check when it dies again
By draining the battery slowly I mean no light in the screen, no running programs and universal in closed state, flight mode and just one thing to check if it was alive or not, play some music in WMP in repeat mode, when it stoped playing it was time to have a litte more eletric juice until I could boot it up and start the music playing again.
When I have the final results -> when the universal goes down I will post the solution in the wiki
Again this may depend on the batterys but since there are so many people buying new ones you maybe want to try this solution too.
Oh and by the way I solved an "other" problem while trying to solve this...
Besides the tests on the battery like freezing it over night, taking the power level pin etc, I've started to think it was a problem from the rom so I cleaned the Universal doing that "task 28" thing and the result was solving the problem that I was having with the battery status (now home screen plus plus) it was not getting the cpu using percentage when in the past it did. Now with the cleaning reg whatever It is showing again the cpu using %
I don't know if you use this but it has a cool functionality, posting the cpu using % at the top bar of your universal can tell you how much the universal is working all the time, enabling you to notice when it is working when it shouldn't, normally some stupid background program that didn't go off...
hi there. I have two same unis, and three batteries. two standard, one big capacity 3200mAh (personally I dont believe it have such capacity, it is some china crap). but all three had that issue (uni shut down when capacity still showing more as 30% or more %). tried to deplete the battery completely (when it wont boot, I put device to bootloader mode and wait untill died completelly). now it show again 0% on all three batteries. I dont want to say, that your method is bad . no, I am just a lucky one, where the "wiki" methods worked correctly. and I think it is also important sometime charge the battery completelly, not only for couple of minutes, but until you see green light. when you deplete the battery completelly to zero (it is never zero, electronics integrated on the batter doesnt allow that) charging to full take much more time as before.
powerdetect
one more thing, you can test, how much capacity your battery have. it is simple utility called power detect. you can find it in THIS thread or as attached file. just copy to device and run. the test will suspend itself after one hour, so set all settings as needed. it will automatically create file, where you can find all important information. before you use it first time, charge your battery to full.
Thank you for the reply, My battery still dies at 30% but no more at 70% and 50% and it lasts 3 days/nights in a row.
I tried the boot loader mode but it seemed it had a timeout, instead of dying from battery losse it died from some kind of time out :/ because I was still capable of juicing some more battery if i went again to boot loader...
I will check that app, thnks again
wat i did..
well my battery used to shut off at 95 above present...wat i did was drain the battery with a 12 volt motor, took me a complete day for it to discharge, then i put it in the freezer, was suppose to put it for one night but i actually forgot bout me putting the battery in the freezer n i remembered after 2 days. then i charged it which also took around 18 hours to charge now my batter shouts itself at 70% n i can listen to music for 1.5 hours. which is a lot from a battery which was shutting at 95%
I have no UI like SPB MS installed. I have even removed the HTC Home plugin from today screen.
The battery of my device drains too fast even though its on 'Hibernate'. From 100% to 20% in 24 hours.
Using WM6. Could it be the 2GB storage card causing this? What else could be the reason?
Thanks
Ways to boost your battery's life
Turn off "Receive all incoming beams" (Settings->Connections->Beams)
Set the screen to the lowest brightness and have it turn off the backlight in a short amount of time (Settings->System->Backlight)
Have the PDA turn itself off in a short amount of time (Settings->System->Power)
Keep Bluetooth and Wifi turned off unless required
Force the PDA to use GSM instead of UMTS (Settings->Personal->Phone->Band)
Increase the amount of time between checking your email in Outlook
Ensure the battery is always charged via the proper charger (ie not a Car Charger or by the Computer Cable) and that it is allowed to drain to below 60% before being charged back to 100%)
Clean out your "\Windows\Start Up" folder - only leave what you need
If the battery still lasts a very short time
Purchase a new (possibly extended\larger) battery (Have a look at eBay - but be careful, poorly made batteries can deteriorate quickly)
Install a new (more vanilla) or the same ROM again
If you have followed the above advice, but the battery is still lasting a very short time (ie <24 hours) check out the following wiki article:
http://wiki.xda-developers.com/index.php?pagename=UniversalBatteryIssue
Hope it helps,
If you've had your device for a long time and used the same battery, it could be that the battery is just getting old and not working as it should. Though it may not be the problem, you can usually get a battery for your device on amazon.com for pretty cheap (around 12 USD for a Kaiser).

I have tried 2 different Windows Phone 7 devices. The Focus and LG Quantum.
I have been completely floored at how long their battery life is. Is this just because I have only evaluated them for a short amount of time.
I have compared them to my EVO and I will have to charge my EVO 3 to 4 times as much either one of the phones.
My usage has been
Between 30 and 50 text in this duration.
5 to 10 phone calls
Blue Tooth usage for audio/calls
Wi Fi Usage
Listening to Music
I agree completely! My Focus has never let me down, even during a day of heavy usage. These people you see on the forums complaining about battery life must not be coming from Android phones.
I have a suspicion that WP7 is designed to hit the network much less in the background and when the screen is off, thus using less power throughout the day. My only proof is that my monthly data quota is being depleted almost half as fast with my Focus as compared to my Aria.
I'm getting about 50-100% more battery life out of the Samsung Omnia7 compared to the HD2 with the same usage.
...but I'm also trying to treat the AMOLED screen right, so I mainly chose applications with a black background to make it last longer.
Omnia7 is lasting 2 to 3 days, HD2 lasted 1 to 1.5days.

hmm, my omnia 7 lasts 1 and a half day at maximum with low usage (just a few calls, sms and mails, a little surfing the web). all with dark theme and all apps with dark background...
at average it lasts exactly one day, definitely worse than my desire with a custom rom
i woundered about this cirumstances, because the battery is bigger than my ex-desire.
what are the biggest battery consumer in the os? maybe i have missed an important setting? (gps is off...)

My settings are:
Bluetooth always on (but not connected, just the 1hour I'm driving my car each day it connects to the navigation system automatically).
WLan always off
Location service is always on
I'm using the phone for approx. 10 SMS, 30min calls, 1 hour RSS feeds/calendar/internet and a bunch of EMails each day.
When listening to music, playing games aso. the battery is dying earlier but these are exceptions.
The thing that needs most of the power is the screen. Whenever you switch on the screen, the battery is draining fast. When browsing the web (white background) it is draining even faster.
Also, switching from UMTS to GSM needs power, in areas with bad reception the battery will drain faster than with steady reception.
also "find my phone" will use more battery.
i cant seem to put my WP7 down and still get @ 8 hours out of it.
Does anybody have problems when charging via usb through the laptop?

Weird... my battery charges - slowly - while connected via USB, even while I am tethered.
it's probably a silly remark but it of course won't charge if your pc/laptop is sleeping/off.

Yeah, I had that problem too. I left the phone connected to my PC overnight, and the phone drained much more battery than it does normally (unconnected).
Otherwise it drains about 50% per day for me.
I found the same for charging off of my sleeping laptop... the battery drains itself over night. My fix was to close my laptop, let it sleep, then plug my phone into it. It stays trickle charging over night and has been fully charged for the last few weeks now.
Anyone know where to get an extended battery? Thanks.
I can't even find a place to buy a regular battery for the phone. I'm not sure if I would need one, but it would be nice to have. I'm in the habit of charging it the last hour I am at work so no matter what, I'll never run out of battery even if I go somewhere straight from work, but a spare battery is always a good thing to have.
I have a wild guess as to why not.
I noticed this phone battery has the "near field communication" labeling on the BATTERY. The other phone that I'm aware of having NFC, (the galaxy s2) does NOT have this wording on the battery.
Why did I notice this? I randomly read that there is an SD card manufacturer that is putting NFC chip's into their microSD cards, and even some ipod cases are getting NFC chips built into them as well.
I don't know too much about NFC, but with the labeling being on our battery, and not the S2, I kinda think our NFC chip is actually in the battery, and not the phone itself. If an NFC chip can be put into an SD card or case on a phone that never had NFC to begin with, I don't see why it couldn't be put into a battery, especially since one of the terminals might not even be for power, but just for an NFC connection.
That's my theory, I could be wrong!
you're probably right. This is how it is with the Galaxy Nexus, also built by Samsung. I hadn't noticed the label, but I also wasn't looking for it.
I'd be curious to find out what an "extended battery" for this phone would look like. I'd be all for it so long as it kept NFC and didn't bulge out of the back
I'd be interested to find one. Being on a stock rom and standard battery, my battery drops about 5% in five mins just checking Facebook. GPS drains it another percent per min it is in use. Half way thru the day my battery is dead. It really sucks having to carry around a charger. I'm also using juice defender and other tweaks I know to save battery
I'd bet you a waffle cone your screen brightness is set too high.
Forget most of those "battery defender" apps, especially if they are those stupid task killing applications.....a program being in active memory is not necessarily actually doing anything, which means it is not using your battery, and if it gets killed, if the OS needs it open for any reason, it having to be re-opened will just use cpu cycles anyway
I'd agree with most people that using the automatic brightness option is very annoying, it's really sensitive and it also tends to make the screen not be bright enough. Having said that, using any of the many available brightness widgets can be a very good thing.
The stock one is not so bad, personally I've been enjoying powerful control, http://goo.gl/2vZXl but I've had great battery life and easy readability if I use the brightness setting where it looks like a half moon.
If you're outdoors in the bright sun, you'll need the screen to be as bright as possible if you want to read it, but otherwise it's fine. The screen brightness is always the single biggest battery usage factor.
Personally I've always disabled the haptic feedback as I think it's annoying and I'm sure that using vibrating alerts is also a huge battery drain.

My screen brightness is at zero without automatic brightness on, and im not using haptic feedback. The phone battery is fine if its just sitting over night, but as soon as I turn on GPS to use maps for 5 mins or to check facebook the battery just drops a % every min. So i guess the phone is fine if Im not using it, but then whats the point?
You're exaggerating.
I've never had a phone battery drop 1% per minute.
Look man, I just spent 5 minutes playing music at max volume, while getting directions to 8 different places in google maps, sent two emails, downloaded a new app from the market, and received one text message.
Battery level after all this? Still at 100%. Does that mean I can do this an unlimited number of times? No, it does not.
Frankly, I don't believe you. I've used this phone, and my previous phone for playing movies at full screen brightness with the audio being played through bluetooth to my stereo headsets. Does it effect the battery status? You bet it does.
Two weeks ago when I last played a snes game on my phone I did so at full screen brightness over bluetooth to a ps3 controller. When I wasn't playing the game I was sending or receiving text messages and had vibrate on. I played super metroid from the very beginning to almost through the end of the game. When I play snes games on my phone I tend to use quick save and quick load and frame skipping very commonly, effectively letting me do things "perfectly" but this is a lot of saving and loading and running the game even faster than how it normally is. I started at 2, and the next thing I knew it was 6:00 and I was supposed to meet a friend for dinner at 6:30.
But for crying out loud you are saying you can drain your battery from 100% to zero in less than 2 hours.
I'm calling shenanigans. I don't think you could even do that intentionally, unless you sat there and forced the phone to vibrate the entire time.
Phone batteries don't last for days like they used to. Batteries have not changed too much in the last few years, but the things phones do, and the screens they do them on certainly has. Stop expecting your phone to last over the entire weekend even when you actually use it.

Something to keep in mind:
When this phone hits 100%, it STOPS CHARGING. Even plugged in, it will no longer be drawing power into your battery, yet it'll still be running on battery.
If you plug it in when you go to sleep, it finishes charging within 2 hours, then it goes 6 hours idling on battery power but it still says 100% until you disconnect it. Then, while you're using the phone it'll adjust as you use it until it gets to the right level. This is likely what you're seeing.
If I use my phone from the moment it finishes upping to 100%, I get great battery life. I get great battery life in general and have been happy with the phone.
Of course, this might be a totally different issue where you just got a bum battery. But it's something worth considering.

I don't believe this is true. I hate to constantly be a naysayer in this thread, but this didn't seem logical to me so when my battery went to full, (when the battery is full, unplug charger text showed in the notification bar) I kept it plugged in and set it to play a couple tv episodes on full brightness while I did laundry and made dinner.
Two hours later, I first looked at the battery status while the phone was still plugged in. As expected, it was at 100%.
I unplugged the charger, waited a couple minutes, and checked again.
Still at 100%, which completely makes sense because I've never had a phone that behaved as you've described.
I also would have noticed the battery dying very early, *every single day* because my habit for the last week or so has been to plug the phone in when I go to sleep. I have an app called syncme that pulls files off my computer such as music and video while I'm sleeping, and on average it transfers about 6 gigs of data this way, every single day.
I don't know if you've ever transferred 6 gigs of data on a phone via wifi, but yes, it's not exactly battery power friendly.
My phone's always been 100% battery when I leave for work, just like my last phone was where I also plugged it in at night.
Just saying!
So you guys know.. I have galaxy nexus and the blaze and the batteries are the same so you can order a battery fro the nexus and it will work with the blaze

Just did an ebay search for Galaxy nexus.. You might need to clarify which model number as there are various Galaxy Nexus batteries listed per Nexus model on ebay...
Galaxy Nexus GSM I9250

Actually he is pretty close to the way it operates. The way your phone gauges battery life is similar to your car with gas. When the meter reads 100%, it is really more like 98%. When the battery reaches true 100%, the phone will stop charging the battery (but will run off of USB power, not the battery). They do this to account for small variations in the many variables that affect a battery's performance (like temperature). Likewise, your phone will read 0% before the battery is truly completely drained (this is also to protect the battery - they don't like being charged to 100%, nor drained to 0%).
This could also greatly affect your previous test on battery performance. To get a more accurate result, let the phone drain to about 60%, then test the time to drop a percentage point.
What you are talking about is a suggestion that the battery meter doesn't necessarily update it's strength meter all of the time, and you even say that the phone runs off the plugged in power at this point.....

His entire post is incorrect, and has nothing to do with what you are talking about either.

Before you discredit anyones post, you should understand how many battery chargers work, and the importance of them shutting off following a complete charge. Here is a quote regarding Li-ion battery maintenance :
Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
Many chargers have this feature built in to avoid any overheating and/or damage to the cell. I'm not saying this is the case because I have not tested whether the battery charging circuit in this particular phone, or it's charger operate, but I will say that this has been the case in MANY of it predecessors.
That being said, I think an extended battery would be a welcome addition to the options of this phone. Mine too only lasts a day at it's best. Perhaps not 1% a minute...but then again who knows?
