Battery life

Definitely look forward to the results.

Although not a controlled experiment, here is a description.

Charged the phone through car charger while driving to the Marathon start. Started with 99% battery at 7 am. It's 1230 now, have 53 % battery, and here is what I did.

Mapped my ride with an app that used 3g and GPS the entire ride. I used that for about 3 hrs and 15 min.
While at the event today I took about 25 pics, some while the app was still running in the background.
Uploaded a few pics to face book.

Not bad. The only problem was that the phone almost overheated. At the end when I was naming my ride and posting it to the app's website, the phone was responding at an incredibly slow pace. Also the camera app was acting funky. The phone was in an otterbox, attached to my bike's phone mount, exposed to direct sunlight, and running that app contstantly. With an overclocked cpu, what do I expect?

That is truly impressive to have constant 3g and GPS usage and only lose half of your battery life in over 5 hours. I used a similar app when I was running and I was losing roughly 10% every 25 minutes. Chalking it up to what must be a bad phone. I have tried it all and hopefully my exchanged phone will have much better life.

Are you using any of the Smart Actions?

No, I haven't really messed with smart settings yet.

As someone else somewhere on the forums pointed out, the first few days or maybe even the first week or two of use is probably not a good time to make a judgment on how long the battery lasts, because you spend so much time getting the to know the phone. We take a lot of time setting it up, adding contacts, experimenting and playing. Then when the newness wears off and we settle into our normal routine, THAT'S when I think I would make my judgment. When I first got my original Droid, I was appalled at how frequently I had to charge the battery. Then after I stopped fiddling with it constantly, it would usually last all day, and I'd just put it on the docking station at night.


I am accustomed, however, to carrying a spare battery with me at all times, and getting the Razr knowing that the battery can't be replaced made me a little edgy. But I think I'll just get one of those power packs that recharge the phone when necessary, and stick that in my purse.

I thought about getting one of those too until I figured out with this phone you probably won't need one unless you're going on a long flight where you can't charge the phone. Mine is at 40% right now after 25 hours. I'm not away from an available power source that long!

If you want the battery to last longer, you must completely drain it until it dies, you only need to do it once. I just c did it last night for the first time, had it since first day, battery life got better each day, but draining it the phone now reports the correct amount of charge, doesn't do anything for the battery, and i'm at seventy percent with 12 hours of medium to hard use. I think before I did this the battery shows like thirty percent, but in reality it was a bunch higher. Last night it showed fifteen percent, and took me two hours to completely kill it, Netflix over 4g and 6 games of robo defense, I'd bet the real percent was around fifty percent. Try it, you'll see

A few posts back someone asked if both wifi and cell data radios can be on same time, on the razr the answer is yes. Noticed that first time I used wifi, only good reason would to receive picture texts or mms.

Not to beat a dead horse but the two most important things to do to make battery last on this phone is to run it until it shuts off, just do it once, if it takes much longer than you'd think with the level its reporting, your battery wasn't reporting the correct amount of charge. Second, setup these two smart actions.

Trigger screen off and charging no
Acton wifi cell data GPS and sync off

2.
Trigger screen on OR timeframe all day
Action wifi on, cell data on,GPS on, sync on


These will turn off all radios when your NOT using the phone, the screen is off and its not charging. When you turn on the phone to use it, everything turns on, huge savings for the battery.

On the second action use the trigger all day, not screen on. Also if you use a location based action, like for home wifi, set this one up, connects and turns off 4/3g radios.

Trigger location (your wifi)
Action cell data off( you still receive txt and calls)

That simple

This is correct. Battery should drain Completely one time or once in a while to keep the battery peak. However I know that the phone companies say to recharge at 75% drain. This is good practice but also better to let it die completely and recharge to full without turning it on. I do this twice in a row on new batts and then bump charging is OK when time is limited..Thanks...I won't get into the whole depth of lithium batteries and maintenance ...lol but this is just for people that may bump charge from day one..Peace!

Tried the location based Smart Action for my home and work. Not satisfied that it needs to keep Wi-Fi enabled as Wi-Fi seems to use more battery incrementally more than the power saving reduction achieved. Not a good trade-off IMO but I could be wrong.

Thinking that in a matter of a few weeks, us RAZR users will have figured out the best optimization set up for Smart Actions. Can't wait! :icon_ banana:

Wifi uses less battery than cell data

Same here but first 100% charge I delete the batterystats. Bin then drain till power off then fully charged while device is off.

There's no WiFi at home or Work so this action is basically worthless to me right? Really wish it wasn't a default condition to the location based trigger as GPS would be sufficient to trigger??

Ultimately I think the best way to save battery is to manually toggle your settings on the fly if you don't mind it.

So what would you say average use discharge on this phone is? About 5-6% per hour?
