Sure fire way to kill/shorten the life of a Li-Ion battery. They do not like deep discharges.

He may be right if this is true.

Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while

He's absolutely right ! :good:

Read my post. For dumb Li-ion batteries, this may be the case. Smart Li-ion batteries have a countermeasure in place that keeps a reserve of power to prevent the damage. I agree that deep discharging does not improve the performance of a Li-ion battery, but the fuel gauge on our phones is horrible, so it is necessary at times.

Edit: One of the advantages of Li-ion batteries is that they can be recharged on a partial discharge, without a memory effect. Full discharging may not be optimal for Li-ion batteries, but it certainly won't "kill" your battery. The countermeasure I mentioned above largely mitigates the issue.

These batteries last 500+ full discharges and THOUSANDS of partial discharges. If you want the longest lasting battery always charge around 70%

Yes, but from what I have read, Android only discharges batteries to 30% or so. iPhone's to 40%. When they ported Android to some Windows Mobile devices, they didn't have that protection, so peoples batteries were discharged and refused to charge again without a high current. That's bad. But it'll never happen to ours. The discharge method does nothing to the battery, but it may have a positive effect on the battery stats.

Exactly! When your phone says the battery is at 1%, the actual charge in the cells is closer to 30% or 40%.

I didn't get to see your post as I was writing mine at the same time
Bottom line for me is that I charge it when it needs it and use it until I charge it. Then I replace the battery when I think it's used up.

It's all good, man

 

[clay101eve]

From what I've read, "calibrating" your battery by doing a "full" discharge/charge cycle does nothing for our phones.

As far as what's best for battery life,lots of conflicting information. Personally I try to keep it above 60% when possible. If it gets to 10% oh well. It's all good. I'll have a new phone before I wear out the charge cycles of my battery.

I just switched back to ShoStock2, I just kept running out of memory with his one and it was getting really laggy. I'll try again in a month or so.

Nice ROM

I have used this ROM for 5 days now. I waited before I post the feedback. This ROM is good in lot of ways. I came from stock ICS release. I am using now using shostock3 v1.6.1

1. Absolutely no heating issues so far which was always a problem on stock AT&T ICS release.
2. The device is buttery smooth. Most times the device is smooth except few times where I see the Touchwiz crashing.
3. Battery life is very bad. Looking at the battery performance, most of the battery is consumed by Android OS and display screen. I have reduced the brightness but still there is lot of battery lost here.
4. On clicking the power to unlock the phone, the screen doesn't come up fast. its kind of slow. It will be nice to get the wake-up/sleep effect that is seen on Nexus 4/Galaxy nexus device.

Will come back and update the performance and issues soon....

Thanks for the ROM, OP :laugh:

So I'm putting you to the test here SHOman. My wife's iPhone is out for warranty work (stuck home button, it seems to be a recurring problem) and because she's considering getting an S3 I told her she could use my S2 which is running the most up to date version of this ROM. I told her it would be as close to an S3 as she could get without actually having an S3.

While she's using that I'm back to my old Atrix running CM7.2. I'm hoping her time spent with my S2 running this ROM will cause her to switch to Android. Fingers crossed, we'll see.

Awesome.... I think she'll be happy.

There are many different and conflicting things that people say about Li-ion batteries. I mean no disrespect, but I've seen no evidence to support your claim. The fact is that smart Li-ion batteries are not completely discharged when they say that they are. the always keep an unusable reserve of power to protect from deep discharge damage.

Yes sir

yes sir BUT its good to perform a full cycle here and there for the phone's calibration in my experience.

Running out of memory.... that make no sense. You are the first I hear of that.

This happened to me at one point and was caused by a corrupt CWM backup; the media scanner kept scanning the backup directory until the memory was full. Long story short, I removed the backups from the phone through the CWM menus and things are back to normal on that front.

hmmm.. that makes sense... especially with the different file versions that CWM was using at first. Now it's all default to tar....thank god.

Old back ups... corrupt files, retarded files names...lol... thumbnail files corrupt or missing.... these all lead to media scanner running away and excess system storage usage.

Long & short of it...i'm really liking this ROM!

Does anyone know what the "l2_hsic" wakelock is? It shows up on my phone periodically and usually kills my battery when it does.

But the whole battery discussion didn't offend you?

I've checked Google and it seemingly has to do with the modem waking the phone and switch between 2g/3g/H+. Seems to be mostly a Samsung issue.

Here a good explanation I found.... no real fix... many solutions I guess.... people have tried a lot of things....

HISC is the interface that connected the main Soc processor ( Also called Applciation Processor AP) to the modem ( 3G or 4G if there are two modems separately )

HSIC is used the standard USB core library. And it is stanrd given by usb.org. The HSIC by itself consumes very less power and is one of the very power efficient and space efficient ways of interconnecting chips. Currently common to Qualcomm and Sammy Exynos architectures.

The reason you seeing too many HSIC wake lock and other wake us's is due to the fact that the HSIC interface is waken up by modem (Normal scenarios are also so many) .

Also one imp reason is EFS sync. A concept : that the new modem architectures doesn't support a flash storage.(Saves lot of cost to manufacturer) .So every time modem needs to store something , it wakes up hisc interface and ask the AP (Main processor) to store it for him.

So this CP storing via AP is a fairy frequent activity.

I see the concern over this L2_hsic wake lock. I can say at this point that it is quite naturally and a necessary evil for smooth working of your modem( network 2g,3g,4g ) subsystem.

Hope this is of some help.

I'm having issues because I like to use statuabar+, go launcher, and SwiftKey and SetCPU. I have 0 problems on SHOStock2, but on v3,for some reason, it just uses a lot more cpu and memory than normal. I tried it for 5 days and I just couldn't figure out a happy medium. It might even be because these apps are not optimized for 4.1, but I don't know.

I can record a video if you want to see the difference.

I love all he new features, but I don't want to sacrifice too much of what I enjoy doing. I assumed v3 would use even less ram idling, but I don't think it does? Might have something to do with the Google now search feature.. And the multi Window, and the extra animations.. Just a lot of stuff.
