I bought two samsung discover 730m phones, put a SIM card in both of the same provider. Did not modify the stock ROM at all. The one phone lasts over a day with lots of use or up to 4 days with no use. The other lasts only 8 hours at most with no use, even less with use.
I swapped the batteries and determined it's the phone not the battery.
I have turned data off, bluetooth off, screen brightness down, installed a battery saving app, made sure syncing is off, and still it chews through the battery. Can this possibly be hardware related
Any suggestions of what else to try?

My dad was having problems with his Monet/Lobster 700tv and so lent it to me to have a look at (as I have one too).
I have found that his just seems to consume the battery, it can be empty within a day whereas mine lasts several.
I can't find a software reason for this, the bluetooth is off, it doesn't seem to make any difference if the phone is turned off (so it is not a radio issue?), the screen turns off within a minute.
If I swap the batteries between the phones, the battery in my dad's phone still empties quickly, so it can't be the battery.
If we only had the one we may think it was just the phone, but as they are so different it could be a hardware issue?
Hey Guys,
I am usually just a silent observer on the boards and try and gain knowledge from all these amazing developers but my experience last night has pushed me to vent. I live Atlanta, and a Vendor had offered us some suite tickets to the Falcons Ravens game. Of course I would take those. Knowing this phone does not get the best battery life, I made sure to have the phone fully charged before I departed. I left the office at 5pm with a full charge. Throughout the night I would send a txt here and there and take a photo, nothing too strenuous I thought. As the game was coming to an end I looked down and saw that the phone was already in the yellow, not terrible since it should last me till I get to the car. I’m not thrilled because this means the phone charge has only lasted 6 hrs. I get off the mass transit station and go for my car key…..and it’s not there. I check all my pockets to find nothing. I am now screwed. No car, no phone, no charger. To cut the story short, I had to find a payphone (needle in a haystack) and call collect to my father, who has the only spare key. Needless to say he was not too please coming down at 2 am to get me out of the jam. I am just so furious that the phone died so quickly on me. It seems if I ever go out at night, if I’m not near a charger, that phone is dead within hours. Sorry for the rant, but its just the one major flaw about this phone. My old Tilt would last a couple days ( I know I know, small screen low processor) But a solid day out of these phones would be nice.
Do you manage the battery consumption by turning off unneeded features such as Bluetooth and Wi-Fi? Have you set the screen timeout to a few seconds of idle time? The display is the biggest consumer of battery power. Finally, when I know I'll be away from a power source for more than 6 hours, I put a fully charged spare battery in my pocket.
FYI the Galaxy S has one of the best batteries for a smart phone. With careful use and battery management, I routinely get 16 hours before a yellow warning.
I had much of your same problem in the first few weeks of having the captivate, prompting me to go buy two extra batteries and a charger off ebay ($10). I feel that upgrading to cognition 2.2 and using the task manager to stop facebook and such from always updating has saved a lot of life, and my phone will last a day to a day and a half on a single charge, so long as I put it into flight mode at night. then I just shut the phone down, switch out batteries, and turn it back on.
I have the screen set at the lowest possible brightness (11%). When i am out i never have bluetooth or wifi on. Perhpas there was a runaway app that was draining the battery. I have never gotten 16 hrs though. My max is about 12, and thats if i dont make any phone calls. You start making calls, it just kills the battery life on my phone. I did use to have a spare battery on my tilt, i might have to do the same with this phone.
It's most likely because your phone is not sleeping when the screen is off.
Download the "Spare Parts" app or just enter *#*#4696#*#* in your dialer and check out the "Battery History". If the Running % is almost full (around 80%-100%) during a day's use, your phone isn't sleeping when the screen is off which means battery is draining. Give it a reboot when that happens, but the known cause I've found was that WiFi causes this issue.
Are you sure you weren't losing signal when you were in the arena? When you lose signal the phone constantly searches for a signal causing your battery you drain.
I know in arenas you don't get a strong signal...
Just a thought
Turn on airplane mod when ur not really using your phone..
I have a great battery life. Especially when not using HSUPA. Try deleting your battery stats.
I typically see 12 to15% per hour drain with constant use.... meaning display is on all the time and I am on internet, phone laying idle overnight... 1%/hr tops. I do have a nice signal at home though... ranges from –70 to –85 so the modem is not working hard at all.
For all those seeking good battery life on the G2x do not give up. I was surprised to see my battery last this long. Usually I get about 12-14 hours max on a charge, but my last charge lasted me almost 30 hours! Now this is with light to medium usage... Some calls, texts, downloading apps, surfing the web. But previously I don't think my phone would last this long even if I left it alone.
Reading the forums, I was skeptical about people claiming they had such good battery life, but here is the proof. I took a screenshot of my usage 'since last unplugged'. And there it is... 1 day, 5 hours 32 mins. About 6 hours was when I was asleep and in the morning not much battery had drained. I've never even seen it go to 1 day before. Sadly to say I'm not sure what the change exactly was. But here are some things that I did.
Get the battery monitor widget. Your phone should be idling at around -5mA. If it's higher then something is eating your battery.
1. freeze bloatware - I think some of them are responsible for eating battery. Also apps like facebook, twitter and the default email app are set to sync automatically. You need to manually disable it inside the app settings to keep it from syncing.
2. When i bought the G2x they just swapped out my old sim card and put it in the G2x. I changed out my old sim card and got it replaced. The metal connectors on the new one looked different. I heard somewhere that the old sim cards had trouble locking into some 4g towers and would waste battery.
3. I think this one might be it... I charged the phone with it OFF. Then turned it on and it charged some more, then off and continued to charge it. Then I turned it on and calibrated the battery. Not sure if that last part had anything to do with it. But it seems that charging the phone with it off helps somehow. It might be something in the android os that isn't letting the battery fully charge.
4. I also did edit the framework-res.apk file to mod my status bar, but I don't think that would affect the battery life. I could be wrong?
So here it is... hope this helps someone.
This was my first real day with my LG E900, I am not really that pleased about battery life, I took it of the charger at 6am by 2pm it had about 30% battery left, that was with WiFi and Data turned of, no phone calls and just listening to the FM radio. Now had I these turned on it would of been dead by lunch time I am certain, I come from an iPhone, and that thing with WiFi etc on still had 40% battery left at bedtime, with WiFi of I could get 2 days out of it easily. I am on Mango if that makes a difference, I think this is easily the worst battery life I've seen on a phone especially when WiFi etc all turned of and I've been through iPhones, HTC, Galaxy S2's etc.
Is this normal or what am I doing wrong? Having owned Android phones in the past I already turn data etc of when not being used, dim screen, location services of etc.
Every battery needs to get used to the phone.
Do some full charge to 100 % and drain to till 20 % or less.
repeat this for 3 or 4 cycles. Then you battery will behave very nicely to you.
Also check whether your GPS is turned off.
some apps use your battery in the background. maybe one of them is the one that drains your battery. i discovered a few days ago that i had htc hub on some other like pulse. and there drain the battery too... there are many factors that drain the battery, the network is one of them... is it on GSM or 3G???

Phone is on GSM as have no 3G coverage, I am hoping it'll take a few charges etc to get it going.
I don't get it. This morning on my way to school, I'm using my Nexus, sending a couple of texts and listening to music, yeah. So then when I get to class I power my Nexus S 4G off, I'm talking about holding power and pressing power off, off.
I turned it off next hour and my battery literally drained itself from a good 95% charge this morning to a 63%. The hell happened here? The phone wasn't even on!

I've seen this a couple of times, vampire drain so long as the battery is attached (phone on/off irrelevant). Never got down to the root of the problem, i believe everyone who has had it ended up calling up samsung to get this sorted as it would be a hardware issue no doubt.
However, do test it again, as follows.
Control Test:
-Take battery out of phone, noting charge
-Sleep
-Put battery back into phone, noting charge
Vampire Test:
-Turn phone off, noting charge
-Take out battery, wait 2 minutes, replace battery
-Leave phone off and sleep (for the same amount of time preferably )
-Put battery back into phone, noting charge
No touching the charger 1 hour prior and before turning on. If there is a noticeable difference between the two tests, call samsung ASAP. Hopefully you're still under warranty.
Definitely a hardware fault

I have exactly the same problem and proved it to be hardware thanks to your vampire test. (This was only after scrubbing through new apps I had installed to see if they were the cause, scrutinizing battery stats, installing a couple of different ROMs, and complete factory resets and everything - nothing solved it.)
My phone was working fine, then one day, a few weeks ago now, I noticed a sudden battery drain and instead of a day's worth of moderate use, it wouldn't last 5 hrs. Finally did the vampire test after seeing this post and discovered that with the phone completely powered off the battery would drain to nothing in < 6hrs. I verified this behavior with two batteries. The phone gets quite toasty as well, so it's got to be some sort of hardware short circuit causing a constant load on the battery.
Samsung said "send it in for repair" - I haven't done that yet, need to find out what that might cost compared to a new phone. (I'm using a company supplied phone meanwhile.)
Too bad, because I loved my Nexus S - perfect size and shape compared to all the new mini tablet phones out there.
