"Official"? Bionic battery life thread

[ConqSoft]

agreed. I just got almost 30 hours with moderately heavy use, with 5 hours of screen time on - on my stock battery. I could not be happier with my battery performance.

Thanks. Next time, can you click the graph at the top also, so we can see your signal strength, wi-fi use, gps use, etc?

oh got that! sorry i forgot that screencap. I've attached here. You can see about 7 hours overnight where it was in airplane mode, but otherwise all up time.

Currently sitting at an estimated ~58 hours of juice on the STANDARD battery.

For those here, if nothing else, when you are in a WiFi hotspot, turn the 3G/4G radio off under Data Delivery. The Bionic does not disable the radio when on Wi-Fi. As I mentioned in my video you can have Juice Defender do that, but I found Juice Defender to be rather iffy with the way it disabled and enabled stuff, so I just do it manually.

Edited to add the graph. You can see that I'm constantly on Wi-Fi doing stuff even though the screen is hardly used, that's because I queue stuff up and then shut the screen off until it's done. I can still make and receive calls though I haven't done so today. It's just that the radio is such a make-or-break with regards to the phone's battery.

The battery life on the Droid bionic its very good, you must have some things running in the back ground.

Ya I guess I do have a few things running in the back ground. Thats my point I want them there I use my phone. You guys that are claiming 30hrs or even 20 hrs are not using your phone. Im retired and dont need a full time job managing my battery lol. I just want to play and if it uses battery so be it Ill plug it in. I guess what Im saying Moto is full of $ht when there talking about all the good battery life you get from the Bionic like revelated said its how you use it.

um, I *am* using my phone. 5 hours of screen/display on is using it quite bit.

That is what I said. However I don't agree that Motorola said or did anything improper. The battery IS efficient. The screenshots I am posting prove that. As with any other device such as the MacBook Pro/Air, all the battery efficiency in the world goes out the window when you hammer the device. That same logic applies even to the iPhone 4; it may normally last two days on a charge, but there are people that have managed to bring even it to its knees in a day.

You have to understand that motorola built a phone that meets everyone's needs so don't say that they are full of $hit when you your phone is draining the battery to meet your needs.

Sorry if I offended anyone didnt mean to. Im probably one of those people that could bring it to its knees. Most people that have these phones dont have the slightist idea what we are talking about. They just get a phone and want to use it. Which brings me to the statement about Moto the average person just wants to turn it on and play with there new phone and dont even know this forum or any others exist. So given that if you were them wouldnt you say battery life sucks. I say it sucks but I no why its how I use it.

There is no widget or app that lets you turn off 3 and 4g when in wifi?

If I bought a car that was rated at 28MPG, I would view that claim with skepticism. That's because there's too many variables that go into that calculation, and it's all marketing when you boil it down:

• What grade of gas did they use? Yes, this matters.
• Did they test in mountain regions? Flat road? Dirt road? Snow? Rain? Full traffic? Imperfect (i.e. cracked, pothole) road? Curved roads? Speed bumps? Stop lights? Stop signs? Or did they test on a perfectly smooth, flat road that they created for an optimized testing scenario?
• What was the temperature when they tested? Yes, this matters.
• What tires were used when they tested? What was their inflation amount? Were they all inflated the same?
• Did they test with the windows up? Windows down? Sunroof open/closed? Rear windows up/down?
• Did they test with a bunch of luggage or other weight-added items to test drag coefficient?
• Did they test with a clean car vs. a dirty one (MythBusters)?

My car is rated such, and I realistically can get 20-23MPG under normal circumstances. My point here is that testing and rated efficiency is always based on controlled conditions and should be used as a guide, not a guarantee. Same with laptop batteries, same with anything else that has a finite life span.

Any consumer who buys a device and sees some number and doesn't understand that "Their Mileage May Vary" has no business buying a phone like this, and I would also submit that Verizon is part to blame for pushing sales without emphasizing the simple fact that it's all about the individual use case. But regardless of forums like this, some things should just be common sense.

On a side note, over WiFi only for the past 30 minutes, with screen timeout disabled and doing large, back-to-back downloads over WiFi (200MB download of the same package, XP Service Pack 2), which except for calls replicates a "heavy user", my estimate actually increased to 62 hours. I even bumped up the brightness to to try and see if Display would skyrocket; it didn't. At this point I'm 99% convinced that the 3G/4G radio chip is the least efficient part of the phone, and if people just simply work over Wi-Fi they will see some rather significant improvements. Call duration is the only test I haven't done, and I'm sure call duration will kill battery just because it does on every phone.

There was one, a year or so ago, but it never worked properly. It only was designed for 3G. I forgot its name.

I have always wanted a one-button toggle that let me set profiles for "Home", "Work" and "Field".

Home will enable Wi-Fi only. No Bluetooth, no 3G, no 4G. I'd use this also if I were in some hotel that had free Wi-Fi, or if I were using my Mobile Hotspot instead.
Work will enable 4G and Bluetooth. No Wi-Fi. We have Wi-Fi at work but it's dialup speed and I can't get anything done.
Field will enable 3G only. Rarely do I need 4G when I'm driving somewhere, and I use my other device for Bluetooth audio because it has better quality.



I've actually gotten tempted to just learn how to write it myself. It's frustrating, because if I could have such an app I think it would go a long way towards power management for this and other phones...for those that are willing, that is.

The car estimations are rated by the epa and everything that is done is a standard for every car. That's why epa numbers are different than manufacturer numbers.

I think JD does it.
