Ok, for those who might be interested, here are my notes on battery life for my K-Jam, I'll continue updating this for the next couple of weeks so folks will have a decent Idea as to what the battery life may be.
Note that the following conditions generally apply to my use:
Display brightness one click below max
BlueTooth is turned on and used with a BT Headset
Phone call durations are not noted in my logs
Signal level is either max or one level below max for the cellular
I am a T-Mobile User
Exchange ActiveSync is configured for polled access, Monday-Saturday 6AM to 6PM are peak times (5 minute poll period) off peak is a 30 minute poll period.

How to instal, where to find a battery driver? it woul really help me if it works like that guy said:
[...] my battery life seems to have increased dramatically. For instance, I had the phone on charge all day Thursday, received and made a few calls Friday, Saturday, Sunday, Monday without charging, then checked the charge on Tuesday and I still had not far under 1/2 charge. Previously I've had the phone whimpering at me at less time than that off charge with much the same usage.

thx
I upgraded from a Cingular 8125 to a 8525 6 days ago. I was shocked on how bad the battery life was on the first day I had it. Over the last two days I decided to run some benchmark on battery life.
3G on using UTMS/HSDPA – Bluetooth – Direct Push Email
Yesterday my phone had a full 100% charge at 9:00am, by noon it was down to 50%, by 4:00pm at was at 10% and ready to die.
3G off using a slow GPRS – Bluetooth – Direct Push Email – Same apps running as above
Today my phone had a full 100% charge at 9:00am, by noon it was down to 90%, by 5:00pm it was at 80%.
It almost seems that when UTMS is on with Direct Push Email it drains the battery as if you were talking on the cell phone the entire 7 hours before it goes dead. I have read in the forums that a lot of people have the same issues.
I wonder if a firmware upgrade will fix this or if we are stuck with horrible battery life on the 8525.

hi, do you know how i can turn off umts and leave GPRS on? thanks.
With no apps and only the bluetooth on the battery lasts less than 3 hours. Does anyone have any advice.
Try to flash the latest firmware.
And 3g too? Mine only runs bluetooth in airplane mode with no apps and I easily get a day 5am-10pm with constant vibration notifications all day. With conspire screen on or off it's only 3% difference. With 24 Nov update.

Hopefully improving your battery
Hi , I've just purchased a Lemfo lem5. Initially my battery didn't seem very good, but the firmware update certainly seemed to improve it. I think initially I wasn't getting much more than 3 hours.
However, a friend at work recommended completely flattening the battery and leaving it for a few hours. And then charging and leaving it on charge for 24 hours.
I did that on Friday evening. It was already flat by around 7pm. I left it until 9am Saturday before putting it on charge. I took it off charge just after 9am Sunday and it then gave me 14 hours of use with both wifi and bluetooth active and I think there was over 20% left before I put it back on charge ready for work.
Hope this solution helps you.
Sprint finally sent me a replacement phone but it's certified pre-owned and I got it on Thursday. I was at a wedding yesterday and taking pictures for maybe 10 minutes at most but I was out in the sun for about 30 minutes, the phone got up to 43c and 111f so I turned it off after taking pictures and put it in my purse and left it off until I got back into air conditioning and turned it back on after it felt cool again. Did this damage my battery and should I be worried? How long does it take for a phone to settle in to it's optimal battery of how long it will last till it needs charged? My phone before that would last 16 hours or more. I got it Thursday so I know Android is still building files, but how long should I wait until factory resetting the phone or returning it? When I got the phone it was at 75% which I know is good. Since I got it on Thursday, battery has lasted at most 14 hours but otherwise 8 to 12 hours, do you all think this phone has a bad battery and when should I factory reset if battery life doesn't improve. I have disabled bloatware with PDP and I use Greenify unrooted, Lux Auto Brightness, Gsam Battery Monitor, and my Android settings are all set to the best battery saving settings, I do use Power Saving Mode I also never let my phone get below 40% I did check the reconditioned status and it was first activated on July 4th 2016 and it was reconditioned on August 24th 2016. I'm just trying to figure out if the hot temperatures for at most 30 minutes in the sun damaged my battery or phone or if they gave me a phone with a faulty battery. Please help me with all the info you can give. Thank you!
For about 3 or 4 days I have been feeling an exaggerated low of the battery even when I am at rest, the last thing was last night I disconnected at 2:30 am 100%, when I woke up at 8:30 am (6 hours later) I had 94%, days ago it wasn't like that (the WiFi was off)
