I am on the 0828 ezgingerbread. I have wifi sleep policy set to "never", because I need VoIP. This is a G1 with wifi on, sitting on the desk very close to the wifi AP, the battery drops from >90% to ~40% in 14 hours with almost no usage. I checked the battery usage and found "Wifi" used 60-70% power.
This is different from my previous experience with MT3G rom (froyo) also from ezterry, for that the battery drain was about half of that speed I would say, with wifi always on.
Do you also see the same high battery usage for wifi? Thanks!
I'm now with ginsense 2.3.7 from rushnees and i can tell you that it drains the battery.
As i know, wifi for a long-usage is better than 3G in the battery section.Ask to the developer about another kernel.
Wifi alway drain battery if you constantly have it on. If that how much the drain is, you are pretty good. My would drop to the point where I have to charge it.

Hello,
I am experiencing a tremendous battery drain when the wifi is switched on, but the device is not used. The battery is discharged after 12 hours!
With this setting, with WM5, the charge would last 2 to 3 days.
I am now testing how the battery performs when the wifi is switched off.
Does anyone experiences this battery drain with the wifi switched on? Is there a solution to this problem? (I just find switching the wifi on and off manually a little annoying)
Thanks!
I am having the same prob, when WiFi on, but not used my battery drained 6% in 2 minutes
also

Hi, i have an issue about battery drain here in froyo with official rom and speedmod kernel.
I notice a 4% per hour in stand-by drain.
If i check with *#*#4636#*#*, under "battery cronology", watching network usage i find something strange...
the most used application , more than email and everything else, is called "0".
When i try to click on it, watching details, i have a force close.
Is there something i can do ? i wouldn't wipe all data to check if i resolve...
Thank you
The same for me.
I have a big battery draining when the phone is on stand-by. For example this last night, i fully charged it, and in 12 hours the battery drained a 10% without using it, with juicedefender installed and configured to auto on 1 minute every 15.
I think that i dont have the gallery sensor issue, but my battery drains more than i think is normal, and i have the "0" under network usage, and get force close when clicking it.
It's the same for me as well..anyone knows what the '0' is??
I'm on JPA build.
same thing happen to me.........try to off your data plan and it will save lots of your battery juice.........unless u are really checking email on your phone of course this doesnt help!!
is it normal to lose 20% charge in standby within 4 hours? i have almost everything off and it still drain my battery like crazy. Sync is off, data is off, wifi policy is sleep when screen is off, gps off, bluetooth off. Anything you name it i have it off. I have "spare part" installed and looking a the stats i don't see anything else eating the battery life. Only thing i see under other usage. is "Running (33.9%)", "Screen on (9.3%), "Wifi on (100%)" "wifi running (61%). Could it be the wifi on at 100% eating my battery?
same problem here
if data is ON overnight, battery drain is very high, like 20% in a few hours (5-6h).
if data is OFF, battery drain is almost 0 (zero)
in iphone 4 when my data was ON overnight with 3G and PUSH turned ON, battery drain was somelike like 3 or 4%.
Something is terribly wrong.
I love the CM7 build for the milestone, It makes the phone so much better!
but one thing is weird. When I use the 3G DATA (browse sites, watch YouTube)
the battery drains REALLY fast!
For example, today I got into facebook, browsed 4-8 pages, and the Battery
level Decreased by 30%! (FOR A 5 MIN SURFING)
Wifi surfing seems ok.
Is this normal?! anyone else had this problem ???
I have the same problem. using 3G data drains my battery drastically. been using the phone for more than 2yrs now. i wont complain about that. but CM7 is gr8 when it comes to boosting your battery life.
Same thing happens here and i think it's normal. 3G consumes more battery than wifi on every phone i had.
Active 3G consume more battery than Wifi (or 2G) but 30% in 5 minutes is not normal.
You should calibrate your battery with this tutorial : http://forum.xda-developers.com/showpost.php?p=11803458&postcount=10
Did you calibrate the battery after having flashed CM7?
I'm loosing a lot of batterylife when 3G is activated, too.
battery "drain" is normal on DATA. i had these problem too with my milestone.
wouldnt say its a CM7 problem...
for me it is because of the "2 year old battery" + DATA... those two wont work well
Hi all
I tried to cut battery consumption down as much as possible while phone is in standby/deep sleep.
I now manage a drain of around 1%/h (BetterBatteryStats actually reports 0.9% per hour).
This is with Wifi on, everything else turned off. I have my CPU undervolted by -100mV and am using perseus kernel with RipperRom, Radio is currently LL3. The signal coverrage in my area is good (3-4 bars).
What is your drain when the phone is not in use? Best way to check is to fully charge and unplug the phone before going to bed and leave it alone until the morning. You can either calculate amount of battery drained per hour yourself or just use BBS.
Please also mention your configuration (Rom, Kernel, Radio, Undervolting, what Antennas were active during standby and how your reception is)
mine's about the same, 0.8 - 0.9%/h on a good night. CPU undervolting won't help much as the phone hsould be in deep sleep most of the time (CPU UV is only active when the phone is not in deep sleep). my wifi is on 100%, i have a bunch of push accounts, a few pull. using ripper, perseus, default telstra modem, good reception
Not rooted, but overnight mine tends to drop around 5-8%, this is with everything off. I had the HTC Sensation prior to this phone and that practically lost no battery life when on stand-by! So am a little surprised it drops quite a few % from stand-by mode.
yeah that's pretty bad, I would get BetterBatteryStats and work out what's chewing up your battery. I'm pretty sure you don't need Root unless you want to look at the network or process stuff..
I'm using Ripper ROM V8, Latest perseus kernel and LL5 Modem.
I got 3% drain overnight (9.5hours) with wifi and data off.

It might be that location reporting is turned on. You should check if google maps has "Report from this device" activated. If so, it will constantly wake you device and report your location to who knows where. I have turned it off and my battery life has vastly improved
However, 5-8% in a time span of around 8h seems normal. You will only achieve less if u switch off wifi and data
Anyone have issues with high Cell Standby? My cell standby is at the top of my list with "time on 8h 12m" (pretty much my entire time off the charger) and Time without signal is 0% (so i haven't lost connection plus I've been on Wifi at home the entire time)
Ive also only have about 52 mins of screen on time with light use and I'm down to 79%. The drain seems very high considering how I've used the phone. I just don't understand why the standby is so high or whats causing it. Im stock rooted and have r17 Franco Kernel installed, it seemed to have started when I installed the latest r17 but I'm pretty sure it would be a coincidence since the cell standby was always kinda high on my list but not as bad as lately.

If you don't use the phone and keep it away, obviously the cell standby will come first but that much battery should not be drained. I can notice max 2-3% of battery drain from 100% over-night on stock
If you don't charge your phone up all the way to 100%, the battery stats don't reset.
Otherwise I think it's sounds reasonable.
8hr stand by, a little under 1 hr screen, wifi on the whole time.
That's about 9 hours total + wifi for 21% or 676.2 mah used. I usually run with a huge stand by time, not so much SOT. I get about 35%~ a day so I charge up every three days.
If you're on WiFi and cell standby is that high then you probably have a weak voice signal connection. What colour is it on your graph? You can also check your signal level in Settings > About Phone > Status
