Nope, getting same battery drain with new kernel. Around 1,5% per hour.

Nope, getting same battery drain with new kernel. Around 1,5% per hour.

Same here, the modifications suggested further up in this thread (change WCDMA -> GSM(PRL), set band to EURO)

seem to have brought battery drain down from ca. 2% per hour to about 1.5% per hour, but the new boot.img

didn't improve things any further, I'm afraid.

[Guest Simon O]

Hmm well that's 2 people saying no improvement in battery life... That's not good!

If it works better for you and for most people then it's an improvement. Anybody that still has battery drain is more than likely either running some apps that are causing this, GPS enabled, always using wifi etc. People need to stop thinking that CM7 is some sort of miracle that will give them 100% better battery because it's not going to happen. We have cheap phones with cheap batteries. No matter the ROM if I'm using the phone to play games, wifi enabled internet or gps then my phone will last a day at the most. Always has done.

I dunno how much of the thread you've read, but the consensus is that battery life when sleeping is much worse than the froyo ROMs.

Couldn't agree more, anyone who wants a phone battery to last for days get a non smartphone! its bloody amazing what we can do with smartphones.........£100 for all this ability its almost scandalous! :(

Nope, no GPS, no WiFi, no gaming, no apps here.

Just pure battery drain on an idle phone in cell standby.

Same profile on JJ - almost no drain on JJ in 24 hours.

Maybe the new boot.img alone isn't the solution, let's see what N13 / RC2 give us.

[Guest rapidone]

I cleared cache+dalvik cache and flashed the kernel-update over Nightly11 and it works too. :(

So no need to flash Nightly 12 as RC2 is on the way...

I think everyone knows that battery drain will be happening if you're using the phone, it's the phone standby that's sucking power. After 10 hours in sleep my Phone standby and idle equals having the phone on and using it for 25 minutes (10-15%).

I would agree if I hadn't seen the battery to last for a week with the FroYo ROMS.

And I don't "complain" just for the fun of it, it's meant as a heads-up because I'm pretty

sure this CAN be solved, but only when the devs are sufficiently aware of the fact, and

therefore I just can't follow their argument "we don't care what you get with other ROMs"

because when you don't know where it works differently / better you can't find the reason

for it being broken im CM7.

But the main issue is that we've all seen much better battery performances.

(I'm back to FLB for the moment and in 3 hours I've only lost 9% but have played ~15 minutes of Angry Birds, been on the phone for 5 minutes, checked corporate and private mails, twicca and so on. Usually with any Nightly I would have lost ~20% with similar usage.)

[Guest rapidone]

Come on guys. Please stop complaining about battery drain. At the moment it's not even a real beta version and many bugs have to be solved.

And don't forget that our devs have a real lifes too. For this circumstances they do a great job and be sure that they have the same battery draining issues with their Blades... So be patient, add your suggestions/bug reports to the official tracker tool and wait for the "patch supplied" news...

We're talking about the standby life Flibblesan. The in-use battery life is fine.

And it doesn't need to be 100% better. It needs to be not 4 times worse than your own (or any other rom) :(

With no partial wakes and phone not waking from buttons (so is asleep). Heck I posted 2 logs on the bug tracker where it did absolutely nothing software wise for hours with the battery just crashing down.

Here here! Do you know how I overcome any battery drain? I plug my phone in overnight :(

Thanks for all the hard work guys,

[Guest JimJam707]

The new boot image doesn't improve the battery life. 11 hours standby (9 of them on airplane) and 19% lost. :(

That's pretty good for a smartphone.

[Guest targetbsp]

All Froyo's and stock would drop about 1% under the same conditions. :(

As for those who doesn't think the battery life matters. We all have our own ideas of what issues are important to us. I don;t care about the hanging up bug because I have a tasker workaround for it (and I have posted it here and on the bug tracker) but I don;t complain about you guys complaining about it. I think the level of excitement around any potential battery improvement and the number of people who then post it doesn't work (and hence people keenly trying potential fixes) indicates that a good number of people are worried about it. Even if you aren't.

Personally, the standby battery life is my number 1 issue with the rom. I don't think it's more important than anyone elses issues but I'd ask other people to show the same respect and not dismiss issues we consider important as unimportant.

For a smartphone in use, but not for one in idle / standby / flight mode .

Really? I lost 19% this morning playing a GBA Rom on my phone for 1 hour :S

Whilst sick I had the Blade in standby for 8 days on Froyo. With CM7 I can barely manage 2. Whilst 8 days is unrealistic use (I normally get 3 to 4), power lost unnecessarily in standby is power that cannot be used when I do need to use the phone. It'll affect everyone that isn't using the phone permanently from charge until flat - just by varying degrees.

My main issue: the phone doesn't last throughout the day (from 7:30 AM till midnight) for me without additional charge with CM7. And that's one of the show stoppers (the other one is the screen off after call but that's not really happening with Nightly8), this is why I am back to FLB for now.

(Since the issues are reported all I can do is to follow the progress on those.)

[Guest Zythus]

I dont really care about battery drain. If phone can last 1 day, then its good. Phone needs to be charged every day.It's smartphone with a good, big screen :(.

And I love ZTE :( and this rom.

I was thinking of getting this thread closed and starting afresh when RC2 comes, I think 101 pages just steps over the easily usable mark. I need to do a nice big sort out of the first post, with the added benefit of it being read. And then, when RC2 comes out we easily relate to the first post because we'll be dowwn that end of the thread anyway, and less trawling will be required on my part.

Do you guys think this is a sensible route to take?
