Can the Evo handle 4g, or lack of better?

[jerrykur]

Hi,

I noticed my wife's Epic seems to handle 4G better than my Evo. She leaves her phone on 4G all the time and still has plenty of battery life at the end of the day. The Epic seems to sleep the 4G radio and only check for 4G availability every so often. Also, when it detects Wifi it shuts down 4g And the routine that attempts to locate the 4G service.

In contrast, the Evo seems to check for 4g quite often and when it is not available this tends to drain the battery. Also it seems to shutdown the 4g radio when wifi is present, but not the routine looking for 4g, which will never be detected. As a result, the battery on my Evo is dead in 6 hours if I have it on at home, where it sees the Wifi, with 4g enabled.

Does anyone know how you can get set the Evo to operate more like the Epic?

I added this the end of the battery life post, but I think it will get answered sooner as a separate post.

i have not use for 4g the entire day, my EVO leaves home at 745am and returns around 5 with minimal use during the day. I will leave my 4g on all day tomorrow to see with how much batt i return home

I leave my 4g on all day and my battery life is not that bad. To me it seems to die about the time as it do on 3g and I'm a very heavy user

i dont know about handling 4G better, the Epic might handle power management better, but i have found in many cases the 4G drops out on a Epic more often than an Evo. Here in Daytona Beach, ive seen plenty of Epics in the service center complaining about not being able to maintain or even establish a 4G connection but i never see Evos about 4G

I wonder if it is my ROM, MikFroyo. Also, do you guys have solid 4g service? I go in and out of 4G all the time here in the SF Bay Area,

I'm using the same Rom. I to get spotty 4g service.

I thought the software update back in December was supposed to rectify this
frequent 4G radio scanning issue?

Not that two people seeing the same thing makes it a coincidence, but maybe you all should try a different ROM to see if the 4G behavior changes. I've never run the MikFroyo ROM and I've heard nothing but good things about it. Just saying it might be worth flashing a rooted versions of the stock ROM to see if you get better 4G performance/functionality. This will either eliminate or point directly to the ROM being the cause of the problem.

Another suggestion is to nandroid backup the MikFroyo ROM, do a full wipe, then reinstall the MikFroyo ROM and run it without loading up any other apps. Turn your 4G on and see how it does for a day. If you get better battery life like this, then this indicates your battery drain is probably coming form one of the installed apps and not the 4G radio.

The other day I left 4g on for 8 hours and with normal use my Evo lasted 15 hours before I hit 20%.

Mine work very well... I can't see any difference in battery life when using either.(3G or 4G)

Have you updated "Data profile" lately. If your phone have to be searching for 4G signal a lot, then your battery won't last at all.

What does the data profile do?

As I said before we drop in an out of 4 g coverage. You can drive 5 miles and go in and out 3 times.

It would refresh your internet connection. However, It seem like your problem is not having a solid 4G connection.

The connection would be solid at home if it were on. We typically see full bars of 4g once out of the range of the home Wifi. One of the problems is the 4g indicator goes away when the Wifi is detected, but it appears that the code that checks for the 4g is still operating.

At work I have plenty of 4g signal outside, but it drops dramatically inside.

Even where I am I have the same thing happening to me sometimes. I don't think you can get away from that once you're using a network connection. I usually tap on the 4G icon on the left side of the screen to have the 4g radio scan for network connection.

Sprint promises that by end of 2012(which only sounds far) its 4G network will be available to everyone - everywhere.

That is a long time away. Probably two phones and maybe a provider away if Sprint does not get LTE.

4g is a new service. it's not easily available in every square inch of whatever city IT IS available in.

4 g is spotty around here too. and 4g defenitly drains the battery faster.
the bigger problem would be connecting to 4g. move over 10 feet and you lose it. move back 10 feet and it don't come back unless you flip the switch off and back on. the phone will say it's on. but it's actually not connected.
