Did I find an app that may actually extend battery life?

[PaulQ]

I have tried Juice Defender and Green Power but never really saw much of a benefit without losing functionality. I just randomly came across "2x Battery" and I MAY be getting some results. I know this whole app based battery saving stuff is hit and miss. I think this one is working.

It has loads of settings but I have only used it with defaults so far. Free and paid version. I'm using free.

So... I'm wondering if anyone else has experience with it and/or letting you guys know it's out there.

I used 2x on both the Rezound and Thunderbolt. It worked well on the T-Bolt, and also seems to help a slight amount on the Rezound. It does create a bit of lag with radios switching on after the lock screen.

Another app that has more features that I like is Battery XL. Great UI, and seems just as effective as 2x.

Juice Defender sucks, and all the other battery savers never really worked, in my experience.

I believe that the built-in power management that the Rezound uses is much more efficient than any previous HTC phone. I'm currently not using either one (XL or 2x) even though they helped a tiny bit. The re-connect lag annoyed me.

My opinion is based solely on my experience, so your results may vary.

This is correct. Gingerbread in particular built a lot of the battery saver things direct into Android. Seems HTC added some more in. There is only so many things that can be turned on and off, and I think Android is doing a fine enough job of it by itself. The only way I think battery savers may help, is if you had a ton of apps pulling updates off the radio all the time.

I must be the only person on Earth who's had luck with JuiceDefender. It's been the app that gets me through the day and not reaching for the charger as I leave work. I just tried BatteryXL and it was terrible, my battery drained quickly during the day with it in default mode. Uninstalled that. Trying 2X Battery now to see how it does today. We'll see, I may go back to JD.

certainly not the only one. i have had great success with jd on my droid x and my wife's droid 3. on her device, the lag required to flip radios back on when unlocking the screen is basically unnoticeable. i have reliably gotten just shy of twice my battery life using jd. on my droid x (pretty slow device for these days), i don't mind waiting a few seconds for the radios to come back on in order to double my battery life. this is, however, coming from people who use their phone primarily as a phone, and perhaps five or ten times per day pull the phone out for internet or other application functions. we are not on the phone's browser/facebook/etc all day long, which would definitely make jd less effective.

those who say jd is "crap" probably don't follow a similar usage pattern, not to mention other considerations regarding their likely reliability as reviewers...

My Juice Defender experience was pretty bad, albeit probable that the device I used it on was mostly the cause (Thunderbolt). If it works for you, I am glad for your success. I paid for the pro version and had to ultimately remove it because it was causing wifi connection issues. I had really high hopes for JD. I briefly tried it on the Rezound, and didn't think it helped battery life any better than stock.

2x and Battery XL did provide some battery saving results for me, but the built-in HTC power management constantly fights for control, sometimes causing connection lapses or preventing radios from switching on at all--especially wifi and GPS.

In the end, the apps are causing minor problems and the HTC power management is what I use.

Every device is different. Every user has different usage patterns. My particular Rezound just doesn't play well with the current battery savers.

I am not trying to provide any app reviews here. Just sharing my experiences like the OP requested. Yours are most likely different.

2x was awesome on my froyo Optimus S but was awful on my Gingerbread EVO 4G - so it may have to do with the OS or may be because of how I use my phone.

I haven't used a battery saver since I got my 3VO.

OP here. I abandoned 2x because after several days it stopped waking my data. That's a problem I had with some of the others.

Oh well. I'll go without. It isn't that much of a difference.

Learn how Android manages power. How exactly can JD tell you it's saving 1.6x battery after being on your phone for an hour? Give an out of the box phone 3 days of normal use without messing with power crap, and it will be fine.

i used my droid x more than a few months before trying jd. been using it ever since, but only when i go out of the house and not to work, the two places where i have reliable wifi. i have been using it well over a year, maybe closer to two, and jd typically shows about 2.0x battery life, and it's been long enough that it's blatently obvious that's about how much longer the battery lasts than when i forget to switch jd on when i leave (and so wifi is also left on, which i otherwise turn off when starting jd, and this is a big contributor as well).

when my wife's droid 3 came, i charged it for her and told her to do it overnightly. she often forgets (it's sitting next to the charger unplugged right now and she's asleep). she did that enough that the device shut off on her twice in a few weeks. it has been running jd constantly since, and it's so virgin a phone and thus running fast enough that the delay upon unlocking is barely noticeable. she can use her phone mildly-moderately and forget it unplugged and still have it get her through the next workday without shutting off, as long as jd is running.

the screen is of course the biggest battery drain. dim it down. don't rely on the "auto brightness" feature without scrutinizing how it's working.

next comes the cellular radio (assuming you're not doing much that's cpu-intensive, which is more typical), but the wifi radio establishing a connection takes perhaps even more than that. once you're connected with wifi, data transfer is easier on the battery. so if you're wandering around town with the wifi radio on, it's frequently searching and finding and chatting with access points, draining your battery.

Neither the DX or D3 using JD, are comparable to a Rezound running JD. Just based on the manufacturers alone, never mind the hard/soft/firm-ware differences.

Without some sort of battery saver, my phone is dead by the end of the workday. With someone, I get through the whole day. This is after months of use.

 

[jbliv63]

After a day of use, 2X Battery did about the same as JuiceDefender for me, equivalent in terms of extending my usages about 50-60%.

You know you guys can do the exact same thing manually right? Add an airplane mode toggle to your desktop and hit it before you turn your screen off. Then when you turn your screen on click it again...or even better, turn your phone off while you're not using it, then turn it back on when you need it....

Been using JD (paid) since the TBolt days and did notice an improvement. Noticed the improvement using your method , also. Problem is that I forget to do the adjustment myself. I keep the JD to help my performance more than the Rezound. 8^)

I've always relied on Team Google to save my battery. It would seem to me that Just having JD or any battery saver app, especially, on a stock phone is making it work harder b/c it can't shut down all the power saving features built in the OS. To me it seems that all it does is lay over top of it and execute extra functions which just takes more juice. Alot of times, I wonder if psychosomatics plays a larger roll in "results" than most believe.

Holy "this is correct" Batman. I used JD for 2 weeks on the rezound thought "wow, it's doubling my battery life, cause it says right there it is" But I still got the same screen on time per charge. I tried for 2 weeks to convince myself.

I do have a way to get guarantee'd better batter. Root, flash one of Scott's Roms, wait two days, and enjoy your phone. I work with my phone, average about 2.5-3 hours of screen on time a day, I'd be dead after about 9-10 hours before root. Now, after a 12 hour work day, I have 15-20% left. This is using the internet for almost 100% of screen on time, 4g, GPS on.

I think the problem is people needed it on 2.1 phones, got used to JD, even after they were updated to 2.3, got a Rezound, saw after the first day the battery sucked, then put JD on, Android on day 2 started to figure out your usage, increased battery life itself, but since JD was just put on, that "seems" like what increased the battery. But, there are still dudes rockin' some task killer, killing every app every 13 seconds, and telling use they still work to increase battery life.

Unless, you tell it JD to put the phone into airplane mode when the screen is off. Then the fun of waiting 30 seconds to a minute for the radio to turn on, if it does turn on without a reboot (my biggest complaint about JD was this, besides it not doing anything).

Interesting read. I actually lol'd at this.

I am charging now and will try going unapplicated to test the water, so to speak. I believe that I get results from JD because I use it on the extreme setting, which is essentially Airplane Mode when the phone goes to sleep, but I still get calls and messages. Can Airplane Mode be configured to do that?

Why do you say configured? Sleep mode on the Rezound should not block incoming calls if enabled . It's in the Rezound owners manual.
