Alright, I own a Sprint CDMA HTC Touch Diamond. The battery life is seemingly atrocious!! I have just been charging it like an idiot (i never let it drain to full depletion) by plugging it in everytime is gets low.
I have not updated anything (got the stock sprint rom and no apps that run in the background), and have changed all of the suggested windows mobile power settings to low (email to every hour/once a day - brightness i left on auto detect - no vibrated notices - turned off all unused data connections).
I woke up at 9am, talked on the phone til 10am, and played with a few things (10 mins pocket express and 10 mins with some stupid apps i was messing with) and the battery is half drained already after charging all night. It is 11:40am right now.
I read that a lot of people are having this problem but that the phone infact won't turn off for hours and hours after the battery shows the (!)-Battery Low notification.
Is there anything I can do to make the battery read correctly as I hate being without a phone, have only had it for a few days, and don't want to drop money right away for an extra wall charger and car charger. Any suggestions or know of any updates I could install to show me the actual battery life?? Any and all help would be great!! Thanks in advance!!

2 days ago, I was applying a Phantom Skin to my phone and ended up getting water between the glass screen and lcd. I let it set overnight to let the water evaporate. Well it didn't and I became impatient and decided to get rid of it myself.
I completely disassembled the phone, cleaned the screen and the lcd, and put everything back together exactly as I had taken it apart. I booted the phone up and everything worked normal.
Fast forward to today. I fully charged my phone using the bump charging method, booted into recovery and wiped the battery stats. After 2 hours of use, it had dropped to 60%. This was with background data disabled, no gps, no apps running, nothing.
So I thought maybe it was the new kernel I installed (KingxKlick Bfs #5). So I booted into recovery (while the phone was still plugged in), and installed the KingxKlick Bfs #4 zip. Everything installed so I rebooted the phone. As soon as it turned on, I am shown the green led signaling the battery is fully charged and my batt statt app on the home screen says fully charged. I thought it had to be a mistake. I open my other battery monitor and it says my current battery level is 100% with 6207 mv.
For the past 30 minutes I have had the phone going as hard as it can. GPS, internet, wifi, bluetooth, youtube, pandora, almost every app, etc. For those past 30 minutes, my battery indicator has not dropped a single percentage.
I am wondering what is going on. Something surely has to be messed up but I cannot figure out what it may be.
Like I said, the phone works like it is brand new (and it practically is for me having only owned it for 2 months).
I just need help figuring this out. This is DEFINITELY not right and could possibly cause harm to my phone.
Not to mention my battery monitor and system panel says the battery is 64.4% and it has never been that cool.
Right now it feels like it is about 90-95 degrees.

Don't have answer but 6207mv on the battery is impossible. seems like the A/D circuit for reading battery voltage is not working. Or the OS is not reading it right.

I am LUCKY to get 8 hours of battery life on my brand new stock Epic.. I usually get 4-6 hours. It will NOT last through a normal day of work without putting it on the charger around lunchtime. I take it off the charger around 6:30 AM and I am usually home by 4PM and have to immediately go and charge my phone.
Even if I put it on airplane mode, kill all running applications, and shut the screen off to standby, the phone still seems to suck battery life down very quickly (~5% in 20 minutes on airplane mode, wtf???).. So airplane mode doesn't help.. And I really DON'T want to put it in airplane mode to conserve battery because then my phone is completely useless -- it won't even ring when my wife calls..
Is my battery defective? Please tell me it is... This can't be right..
Are there processes still running that use lots of CPU, even when the stock sprint "task manager" program shows that nothing is running? Is there anything I can do to improve this if I root the phone? How about custom roms? I would really like to run Froyo/Gingerbread anyway.. If anyone has any suggestions to help to make my battery life not such an EPIC FAIL, I would greatly appreciate it.
EDIT: Also wanted to comment on the SLOW CHARGING. With the stock Samsung wall charger, it takes at least a couple of hours to get a full charge. With a USB cable plugged into a PC overnight, it only gets to about 50%. Compared with my previous phone, the HTC TP2, this is really really REALLY slow. It charged in 30-60 minutes and the battery lasted much longer.
I did notice that Samsung only provides a 0.7 amp charger, versus a 1.0A charger for the TP2. Why does Samsung limit the charge current like this? And apparently there is no nueBattery mod driver for android
UPDATE: JuiceDefender looks very promising. Installed the free version and my battery is only down to 95% after one hour. Thanks for the suggestion.
FWIW, I'm getting about the same 8ish hours on mine running DK28. I'm losing about 4% an hour without touching it. I'm seeing some people claiming insane battery life (18 hours with heavy browsing on wifi) I wish I knew how they were managing that.
Wait, it won't even ring when you're wife calls? and you're complaining?
First, the airplane mode means you switch the phone to airplane mode first then switch it back so you won't have time without signal problem which can cause battery drain.
I am able to get 10+ hrs at least by doing the following
1) use airplane mode trick so no TWS
2) use titanium backup to remove a bunch of stock junk
3) use titanium to freeze certain applications (DRM, MediaHub, Qik etc)
4) Have as few applications as possible that constantly pull data
Just yesterday I had 1 day 17 hours before switching
Yesterday when it finally gave up the ghost with the battery indicator blinking i checked my stats.
I had 1 day, 17 hours unplugged. Screen time was around 2 hours and some minutes. I had 45 minutes of talk time.
One thing i will add is I purchased a charger with two batteries off Ebay. Previously when charging with the stock charger as soon as I pulled it off the charger it would read 97%. With the seperate charger it reads 100% for quite awhile before it starts to drop.
And for the record I purchased this charger and two batteries of Ebay for a winning bid of $0.01, plus $9.95 S&H. It was a steal in my opinion.
Unless you are getting near 12 hours of battery life, one of 3 things is occurring:
1) You are using the phone an insane amount
2) You messed something up
3) The battery is defective
For the record, its almost always number 2.
I suggest doing a Factory reset, which will wipe everything off the phone. Then without installing anything or setting your facebook to update every 15 seconds, see how long the battery life lasts. If it is still only 4-6 hours, then your battery is most likely defective.
well of course it won't ring if your wife calls if its in airplane mode. That radio is turned off.
8 hours? That's it? I wouldn't call that normal, but that's just me...
I just plugged my phone in after 4 1/2 days (108 hours) running on a stock 1500maH battery, running Quantum Rom 1.5 (DK17), no special apps running to disable data (aka Juice Defender, etc.), not in airplane mode at all, with the DRM software running, in other words, a more or less 'Stock' configuration (taking into account any differences in the base Rom).
Granted, I barely used the phone in the last 4 days though

Like I said, barely touched my phone in the last 4 days... been feeling a little under the weather so have been at home a lot and in bed doing all my internet stuff and gaming (pogo) on a laptop instead of on my phone.
Since I updated to the leaked Froyo, my battery life has plummeted. It lasts maybe 1/3-1/2 as long as it used to. Turning off 3G has helped immensely though, so that must be the culprit. I used to be able to leave 3G on while at work and make it to bedtime before having to charge it. Or if I shut it off at night (which I usually do), it would make it through my commute to work the next morning. Now, I'm lucky to get through the work day unless I turn off 3G. Huge difference in battery life for me since updating. I'm hoping they fix this in the official release of Froyo.
Well, I've recently found out that if you flash via update.zip while the USB is plugged in, you'll mess up the battery calibration of your device. This is what I did, and i'm pretty sure the cause of my problems. I did find a fix, and here it is:
siliconaddict said:
This is the procedure that works for me:
The following steps should significantly extend the battery life on your phone:
1. Let the battery drain close to empty (5% or less).
2. Connect the phone to the charger (AC or USB, USB is better) while powered on and allow the phone to charge until the notification LED is green, indicating the device is fully charged and untill the voltage is at least 4187mV. A higher voltage like 4192mV or more is even better. Use a tool like Overcharged or Battery Indicator to monitor this. Note that a green notification LED does not automatically mean that the voltage is good too.
A higher voltage means in practice that it will take longer to discharge, a lower voltage means that the battery will discharge a lot quicker! The difference can be quite significant!
3. Disconnect the phone from the charger and power it off.
4. Reconnect the phone to the charger while powered off and allow the phone to charge until the notification LED is green. The notification LED may turn green immediately. Leave it on the charger for another hour.
5. Disconnect the phone from the charger and power it on.
6. Once the phone is powered on completely (has restarted fully) wait 2 minutes and power it off again.
7. Reconnect the phone to the charger while powered off and allow the phone to charge until the notification LED is green. The notification LED may turn green immediately. Leave it on the charger for another hour.
8. Leave the phone on the charger and reboot into the ClockWorkMod recovery menu and wipe the battery stats via -> Advanced -> Wipe battery stats.
9. Disconnect the phone from the charger, restart the phone and start using it as normal.
From then on always let the battery drain close to empty (5% or less) as often as possible and then charge untill the voltage is at least 4187mV. A higher voltage like 4192mV or more is even better.
Normally you will have to do this only once. However, on all Android ROMs, if you flash a ROM while charging or during the first boot screen on, first boot mucks up the levels Android thinks the phone is at, i.e. Android will think you’re at 100% when maybe you’re only 90% or whatever. So in theory you will need to repeat this every time you flash a ROM while charging!
Better is to make sure the battery is charged before you flash a ROM and just remove the USB/charge cable before you flash a ROM. Put it back in (if you must) after the first boot screen (when the custom screen or whatever shows).

There is a shorter version that also seems to work well:

So combining the two bits of info we've compiled, the best way to calibrate your battery is as follows
1: Charge phone whilst on till LED is green.
2: Disconnect phone from charger, power it off.
3: Reconnect to charger with phone powered off and allow to charge till LED is green.
4: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger until LED is green.
5: Reboot into recovery (back button held at same time as power button) and wipe battery stats.
Battery should now be calibrated.

From what I've been told, you don't have to wipe the stats (you need root to do that) but it helps if you can.
I think this may also stem from interrupting the inital charge of the device. I know I did this on both my wife's device and mine (plus my added fubar of flashing with the USB in). Anyway, hopefully I can report some good news tomorrow.

I get 4 or 5 hours if that. I can barely make it to 6. But i probably use my phone more than the average person. Because i take public transportation and browse, stream, email and have 4g connected on my commute back and fourth.

I've been running JuiceDefender for about 5 hours now and I am loving it.. I still have 75% and I can still receive calls just fine.. It turns off data when the screen is off, but turns it on at scheduled times (default is 1 min every 15 min) so that your emails/twitters/etc can update like normal. The paid version has even more features so I bought it..
Never mind im dumb for not reading his post. Already answered my question sorry.

Decided not to quote the whole thing but I'm in the process of doing this right now! Took 2 hours to drain my batt from full (running everything and keeping my phone searching for gps constantly in a place where it would also be searching for signal makes quick work of a battery!).

Yes, with juice defender I can receive calls and my gmail/twitter/facebook/etc. are all already up-to-date whenever I pick up my phone. It works exactly as before, except my battery is not constantly being drained now.
I guess the downsides are that I might not get a new email notification for 15 minutes, and that there is a service running in the background that may cause some slowdown. Neither has been a problem for me so far. I highly recommend this application for Epic 4G owners. Problem solved, basically.
I usually get 12hrs with moderate use (~2hrs with screen on, half of that is usually on the browser). I turn background data off bc I don't have a twitter and I rarely check Facebook so when I do I just use the browser.
I also noticed that wifi burns more battery on DK28, on 2.1 I would hardly lose any battery on standby with wifi, now I get a 3-4% drain per hour... But with 3g on now I lose less then 1% an hour, it used to be a battery hog.
I’m wondering if my phone or battery is defective. Up until about a month and a half ago, my hardware version 003 Evo used to sleep for 19-20 hours and have 89-91% charge left. I could easily get a full day (for me, 5:00 AM – 9:00 PM) with light to moderate use and still have plenty of charge left. I once got the warning at 15% charge at the end of a 3-hour + phone call and right at about the 20-hour mark. Then things changed.
I now have Azrael 2.1 DC installed with the Azreal Theme, animations, and wallpapers using stock HTC #11 kernel as distributed. The only things synching are Facebook for HTC Sense (synching contacts once a day), Google (normal), News (manual-synch only), Qik (disabled), and weather (every hour). The main Facebook app has everything unchecked and is not running.
I removed the big Favorites (people), Bookmarks, and Friend Stream widgets from the main screens.
The non-default items running has been reduced now to just a few items, but ones that I’ve used all along:
Brightness Toggle Widget, Dr Web Anti-Virus , Documents To Go, and Swype. (Note: Each of these has been through one or more updates since this all began.)
At the current time, if I take my phone off of the charger at 6:00 AM and maybe view/delete a few of the overnight SPAM email, by 8:00 AM (2-hours later) the charge is between 78-82%. If I make no calls or just spend a minute or two on the phone, view/delete 2-5 emails, maybe send a text or two and don’t charge it of course, by the time 5:00 PM rolls around the charge is down to 15-20%. Sometimes it’s less.
I powered on the screen just now and power was at 91%. I viewed two emails, deleting one, in about 30-seconds. Power now at 89%. The phone has been unplugged for 2-hours.
Since I bought SetCPU I installed that temporarily and verified that the CPU isn’t constantly running at 1GHz, but is scaling using On Demand.
Have made backups, tried different kernels, different ROMs (Sense and ASOP) and kernels…it’s all the same, more or less. To add more confusion, my wife’s Evo (completely stock) is now only getting slightly better battery life than mine. Our Evos were pre-ordered and shipped on release day. I’m wondering if either one or both of our phones is screwing up, using far too much power far to quickly, or if it’s the batteries…maybe a bad lot?
I’ve attached a screenshot of the SpareParts battery screen after a full charge. Can someone let me know if the voltage, etc, looks correct? I have several other screen caps showing various info that I can upload later that may help.
If anyone has heard anything that might help to explain this behavior I would greatly appreciate hearing it. Thank you for your time.
New observation. Put SetCPU back on my Evo, and just sat there and watched it for a while. I've observed that the CPU appears to alternate between 245MHz and 998MHz, spending more time at 998MHz than anything else.
I plugged in my Evo, set the screen to not shut off when plugged in, removed SetCPU, installed System Panel, and observed the CPU activity for about 20-minutes.
While the CPU load was very often in the 10-15% range with frequent brief visits to higher demand, the CPU Clock Speed never dropped below 661MHz during that entire 20-minutes and spent a lot of time all over the higher frequencies.
Tried killing everything that I could, even the things that restart; nothing made much difference. Going to wipe eveything, and try some different ROMs and see if I observe the same behavior.
4G may be running in background trying to connect and throwing log errors every 2 secs. Doesnt matter if you turned it off..it keeps going and is a know defect at medium level of support at google site and known for a few months.
Verify using aLogcat or other free log app.
Errors will look similar to
E/Wimax (***): <DC CONNECT> IO error: msg='/1270.1:7771 - Connection Refused'

and wont stop unless you reboot the phone after you use 4G.. every time.
Thank you for the reply! Unfortunately, I live in the Greater New Orleans, LA area, one of Sprint's red-headed step-children, where we will probably get 4G right after Tenney, MN gets it.
Last night, after a nand-backup, I wiped everything twice as usual, and install CM 6.1.1, the latest Google Apps, updated everything and built a normal installation. I left the kernel that it came with.
Using the default 'On Demand' CPU governer, once it settles down it does spend more time down at 245MHz, butif it rises at all, it prettymuch goes straight to 998MHz and back again. I set the governer to 'Conservative' and it appears to be working. The CPU does ramp up on occasion but does not necessarily immediately go all the way to 998MHz...in fact it rarely makes it to that speed.
I'll spend a bit of time like this and observe what sort of battery life I get. One odd thing...while sitting on the charger this morning, my Evo spontaniously rebooted itself...we'll see.
Thank you for your time.

I have been having the exact same problem with my 0003 phone with Nova screen. I used to get fantastic battery live. I would take it off the charger and it would sit at 100% for at least an hour. Nowadays, I take it off the charger and by the time it takes to get to work (10 mins) it will be around 92%. I have tried 3 different batteries, numerous ROMs and kernels with no changes. The only thing I can think of is that a month or 2 ago my daughter knocked my (naked aside from screen protector) phone off of the counter and it fell bottom left corner first onto the tile floor, cracking the screen. I actually went by the Sprint store yesterday and talked about getting the screen replaced. According to him, they don't have parts for the Evo so I am getting a new phone. Hopefully that takes care of my issue. I know that doesn't really help you but just wanted to let you know, I have the same issue
Thank you for your reply! I've been fortunate and have not dropped mine yet. Trying a new 3.70 ROM on my phone and have updated my wife's stock Evo to the same release. Going to observe whether or not this makes any difference.
try doing a full erase and wiping your battery stats (in recovery). see how that works for you.

Thank you for your input. When I created the ROM, I did a multiple complete wipe, and then started flashing. I recently redid everything again with Azrael X v3.0. After a few days, I recharged with the phone off for a few hours after the light was green, and then reset the battery stats. Unfortunately, no change resulted.
I recently flashed the "SBC-net-4.1.9.1-more-havs-v7" kernel, and this has had an effect. When I remove the phone from the charger, usage starts there instead of zooming down to the 88%-92% range. I've disconnected from the charger, and made a short 2-3 minute phone call, and it was still at 100%!
I've charged the phone for a few hours after the light was green, and then again reset the battery stats (though the post for the SBC kernels says that since the battery gets and stays fully charged, no more need to reset the stats).
I am strongly suspecting that the battery is the problem. In order to test this I've ordered a 3500 mah battery. Once I have it installed, I'll fully charge, and then use/charge for several days. I'll observe the battery life during this part, but will then flash to a rooted, but otherwise completely stock ROM, and live with that long enough to observe accurate battery usage.
I'll use the info that I gather during that time to compare with others with the same type of battery. This isn't an exact science of course, but If they get a full day with very heavy usage and I get a full day with little to no usage, I know that my phone is borked, etc.
Thank you for your time, and Happy New Year to everyone!
Well, have had the 3500mAh battery for a while and its not the battery. I am totally baffled. The phone hasn't been dropped, there's not a blemish on it anywhere. Absolutely everything works, there's no 100% wake time...the up time and awake times are different and at least appear to be reasonable.
Both regular and extended batteries have been through the HTC-recommended 'conditioning' procedure, or whatever they call it. I've tried several different Sense ROMs as well as CM6-6.1 (doing double and triple wipes of everything), with various kernels...stock, custom, SBC, non-SBC, HAVs, noHAVs, more aggressive/less aggressive/no undervolting, TM, King's (always wiping cache and dalvik). They don't all run the same, but regardless of what ROM or kernel I have installed, after charging all night I can unplug the phone and leave the house at 6:00 AM, not use the phone at all...100% screen-off time, and by 3-ish in the afternoon the stock battery is at 35-40%. Awake time could be anything from 45-mins to a little over an hour.
Previous to this, and whatever switch got thrown that's causing this, after that same 9-hours of non-use the stock battery would be at least 90%...maybe 85% on a weird day.
With the same 3500mAh battery that others get through 12-hours of extremely heavy use, or with casual use go a few days on, I can use it to maybe answer a couple of texts, quickly view and delete a few emails, manually killing the screen after any activity, and by 5:00 PM, 11-hours later, I'm looking at 40% charge.
The only suggestion that anyone has had (in another forum) was to download the original signed RUU, run it taking the phone completely back to original state, update it OTA, and then re-root (hboot 2.10 with Unrevoked 3.31 or whatever it is, latest RA, etc). The theory is that 'sometimes using the RUU and going completely back to stock is the only thing that fixes some issues'. Has anyone else ever heard of anything like that?
If anyone can shed any light on this in any way, shape or form, you have my sincere thanks in advance.
Thank you for your time.

The theory is that 'sometimes using the RUU and going completely back to stock is the only thing that fixes some issues'. Has anyone else ever heard of anything like that?
If anyone can shed any light on this in any way, shape or form, you have my sincere thanks in advance.
Thank you for your time.

A lot of times its a market app that's the culprit. Make sure you don't have an app installed that keeps your phone awake even when the screen is off. The market tells you what every program has access to including wake issues. After a fresh Rom install / kernel flash........check all apps to make sure none of em do this. Task killers are not the answer......not installing apps with too many permissions helps a ton.

I have been having the exact same problem with my 0003 phone with Nova screen. I used to get fantastic battery live. I would take it off the charger and it would sit at 100% for at least an hour. Nowadays, I take it off the charger and by the time it takes to get to work (10 mins) it will be around 92%. I have tried 3 different batteries, numerous ROMs and kernels with no changes. The only thing I can think of is that a month or 2 ago my daughter knocked my (naked aside from screen protector) phone off of the counter and it fell bottom left corner first onto the tile floor, cracking the screen. I actually went by the Sprint store yesterday and talked about getting the screen replaced. According to him, they don't have parts for the Evo so I am getting a new phone. Hopefully that takes care of my issue. I know that doesn't really help you but just wanted to let you know, I have the same issue

I got the same story from the sprint repair center by me as well. When they told me new phone I asked them "do you mean a referb" they said "yes". I'd rather have my screen replaced then get a referb
Thank you for your reply. Yep, I stopped using task killers of any type when froyo was released due to OS functionality making them useless, and if fact a negative.
So far I haven't experienced any extreme wake-time issues, though I knwo they can be a big problem.
I've tested this by completely wiping everything several times, flashing a ROM and not making any changes so its still using the factory HTC #15 kernel which is pretty well known now for good battery life. I've run it like that for a week with multiple restarts, full charges with battery stat wipes, etc.
So far, no luck, no change. Still hoping to figure it out.
Problem Identified but not yet resolved.
It appears that there is some issue with one or more radios in my phone. I don't know enough about the innerds to know if there is more than one, but whatever receives data downstream is screwed up.
Over time I've noticed that my downstream data has gotten slower and slower. Then I started missing calls periodically, and texts sent to me at 10:30 AM were showing up as arriving at 6:30 PM...weird stuff.
After un-rooting, performing a complete factory reset, and a complete data restore (from the ##3282# menu), the phone and texts seem to be more consistant, but running the SpeedTest app to a server here in NOLA produces the following results:
Ping: 20ms - 30ms
Downstream: 0 - 128Kbs (Seriously, I get "0" often, and 128Kbs is the absolute max achieved on occasion)
Upstream: 1.2Mb - 1.46Mb
After re-rooting the phone, I've tested this in the Azrael 4.0 and EViO 1.8 Sense ROMs, and in CM6.12, and the results are identical. Its very strange that it only seems to affect the downstream rate.
I guess its time to RUU, bring it to a Sprint store, pay their $35 and see if they can fix it.
Does anyone have any suggestions on what I can do to test which one might be bad? Any app you know of that can monitor things and tell me if a rogue app is killing the battery or if the battery is bad?
I was running mik 1.1 and was using it pretty heavily with gaming and downloading stuff. The phone died after about 7 hours. I thought that maybe the rom or cwm or something else might be killing the battery. Something strange though is that, like I said, I ran the battery until the phone shut off. Then I left it off and put it in a wall wart charger for about 8 hours and the status light was still orange. My gf had the phone and told me once she left it plugged in overnight and in the morning it was only at like 50 something percent. I thought maybe the charger went bad so I gave her another one and she didn't say anything else about it. I'm starting to wonder if maybe the phone's battery has a weak or bad cell. I kinda doubt that there's something wrong with the charging circuitry of the phone but there could be, anything is possible. I will probably take it to the repair center and tell them about it and see what they say. I tried looking on htc's site for oem replacement batteries but couldn't find anything. I found lots of aftermarket but I didn't want to go that route.
I don't know if it would not be a good idea or not to try and use my original evo battery just flipped over. I suppose if that's the only thing I have to try and troubleshoot this problem then it will have to do.
Can anyone give me suggestions or has something similar happened to you?
Now let me see if I can find that evo battery..........
Spare parts, in the market if not on your rom by default, had a battery information tab that will indicate battery health as well as what kind of plug the phone detects when charging (usb, ac, or none)

Like danaff37 said, spare parts can be useful. Also try CPU Spy, free from the market, which shows what % of the time your CPU spends at each frequency, but this actually more relevant for determining if your phone is properly sleeping..
For proper charging you can get an app like CurrentWidget or Battery Monitor Widget which tells your the current consumed during usage or current injected during charging, as well as the voltage in mV. Full charge should reach around 4200 mV, and when charging the current should be around ~800 mA for lower % battery left.
Thanks for your input. I found the evo battery and did the same thing as before. I ran it until the phone shut off and then put it one the (same) charger and went to bed. About seven hours later, it was still orange charging. Both times the phone was off. Now something that could be a possibility is the charger is weak or bad. When I put my evo on it, it charges seemingly fine. I should try using the battery until it shuts off again and use a different charger and see what happens. Six to eight hours charging, with the phone off, coming from a dead battery, on a Motorola charger that has a rated output of eight hundred milliamps at five volts. I have others at different output rates and a two amp charger intended for an ipad. Some might say that the charger is too much for the phone. The charging circuitry only pulls as much amperage from the charger as the phone was designed to. Now on the other hand if I put a smaller output charger on, say one hundred and fifty milliamps, it will take longer to charge the phone than usual. "They" say trickle charging is better. Whatever. I will post my results if I find any. Or, I just might trade the phone in for a nexus s or an evo 3d.
I was just about ready to throw in the towel and say the phone was defective, but then things started happening. I will fill you in on what I have done in the meantime. Okay so the flipped over evo battery kinda works but not completely. It will charge but not to 100% and green light. To test this, I took the evo battery out of the shift. It didn't seem to want to go more than 98 or 99%. I put the battery into the evo and after a few minutes the light went green. This was initially off. Then I booted the evo and let it go to sleep. After it booted the light went orange then green after a few minutes. Okay so the evo battery is capable of going to 100%. These charging tests were done with a different charger.
I forgot to tell you, I let the evo battery charge while I was at work and the phone was off. So the battery was charging roughly twenty hours and still no green light. I suspect that even though the positive and negative terminals aligned with the correct tabs on the shift, the center two contacts must be different internally than the shift battery. I speculate that those center tabs are for the battery and phone to communicate to each other during it's charging state. I am guessing that the battery tells the phone it is fully charged and to go trickle charge and perhaps the evo battery wasn't communicating to the phone or the phone didn't know when to say it is done charging. The battery never got hot either.
The shift was rooted, running mikshift 1.1 and the latest clockworkmod recovery. Here is where I suspect that there still might be charging bugs with that setup. I used the pcxx.zip file that when booting into the bootloader, would flash the phone back to stock everything. After trying this and assuming that the phone was back to stock, I kept going with my what the hell is going on with this phone battery charging test. A note about the flipped evo battery. Yes it will work in a pinch but it won't charge properly. Luck has it that the notches in the battery and phone allow it to work in a shift. Only thing is, the shift battery won't work in the evo. The tabs are on the wrong side and the phone's tabs won't allow the contacts on the battery to meet up with the phone's terminals.
Okay, where was I? Trying different chargers wouldn't make the shift green light full charge. I tried the same chargers on the evo with it's original battery in and it would green light after a few minutes on or off. There wasn't anything wrong with the chargers. Oh and another note, while using the battery monitor widget, I noticed that both phones wouldn't pull more than a little over three hundred milliamps of power from the charger to the battery. Interesting to know how much it really pulls from the charger.
Anywho, I tried something different for my process of elimination testing. I actually ruu flashed the shift back to factory and guess what happened..... The battery and phone were charging both on and off all the way to green full charge at 100%! I think I'm getting somewhere with this! All my luck, either it is a known bug somewhere in the forum in a place I haven't stumbled across or I'm the only one that this is happening to. It doesn't really matter I guess.
My conclusion, which isn't scientific by any stretch of the imagination, is that the phone isn't truely back to factory unless you ruu it. The pcxximg.zip doesn't put everything back to stock. I haven't narrowed it down to what is causing this behavior. I don't think it is root. It could be cwm recovery or the rom or both. I didn't try the stock rooted zip either. I suppose I could go further with this investigation but I am too lazy to now. I might root it again and just leave things stock rooted. I might activate this phone in the morning and run it all day tomorrow and see how it acts. I will have to charge it a few times during the day to keep the levels up when I really use the phone heavily. I've written enough for now. Does anyone have anything to ask or add to this topic?
Since the latest update to CWM phone-off charging finally works again but the light never turns green. It charges fully but with the phone off the LED never turns green. It's not just you.

OK. I thought something might have been broken.
Forgive me, I am truly a newbie to Android after having a BB for 8 years. This battery thing is killing me. I am on my 2nd Evo Shift, the 1st one wouldn't last for more than 2 hours with barely any usage so they gave me a new one. This one barely lasts 5 hours. I am barely running anything. I took it into the store and they thought I was going to be running all these programs, but I kill everything. They told me the "battery trick" about turning off the phone and unplugging it and plugging it back in 10 times so I did that but I am not getting any more life out of the battery. My display is constantly using at least 70% of the battery it says even if I turn it down very low or if I set it to choose its setting. Do you have any advice for me? I am not running a task killer, I kill all the programs I am not using. I have no widgets running because I am afraid to use the battery, I only have 2 screens out of the 7 with things on them. I am being help hostage by my cool phone that I want to use but am scared to kill the battery! (sorry for the long post)
Ok if you use a lot apps just close them after (for stock 2.2) . Even on stock you can literally stream music and movies for about 4-6 hours. (sometimes a lot more) . The background info that runs doesn't use a lot of juice , but if you want you can go to your home screen any of them hit menu (but not with the app drawer open) select settings go to accounts and sync turn off background info and just turn it on manually when needed such as the android market . You can also turn off the auto sync and just manually choose to sync , like in the clock (and gmail etc.) it will say no weather after you click it , just hit menu you will see a little sync button option to sync and voila you have weather . So when you visit the market it will automatically ask you to turn it on (background info as will all apps that need this) . And the screen on any android is a battery killer . So when not using your phone simply tapp your power button to turn your screen off and lock (and to keep from pocket dialing lol) . But if all you do is text , emails , and web surfing (surfing drains more but no where near as much as streaming) you can literally do that all day , the screen will actually suck the most power . If manually turning off your apps is too much . Just turn your phone off (not just the screen) and on . If a new app didn't turn off after you start your phone back up you know that will be a problem later . So when not using your phone turn off your screen it will last soooo much longer . I only make a call or two and a couple of texts maybe a few minutes of internet with opera mini . My battery lasts over 24 hrs , but I barely use my phone . Hope that helps .

BTW if you have a bunch of apps running in the background video games etc ... and you charge your phone all night and in the morning it is not charged . You should probably turn your apps off . Or simply power your phone off which shuts off most apps . Then turn it back on . The phone should not take all night to charge , it should only take an hour or 2 . 3 hours max .

i suggest watchdog lite,it monitors cpu usage and alerts you when 1 uses more than your max threshold.if this helps,please click thanks.
When you changed ROMs, did you do it with a full charge? If not, your battery stats file is probably messed up.. Ive used Battery Calibrator free from the market in the past to fix that problem.. I believe a brand new battery on the Shift shows about 4200mV when fully charged or just slightly below that.. Run the app, when it gets close, calibrate (which essentially just deletes the battery stats file and creates a new one)
