Major battery improvement because of update?

[MDteX]

I have no idea how you guys get that kind of battery life. I was at about 15% after 10 hours of very minimal use. Had to plug it in.

I would love the battery improvement you all have. Could service be an issue? At home I'm usually at 2 signal bars all the time.

You are lucky i have intermediate 1 to 0 bars.

service DOES make an issue, if you don't have a decent signal, say 3 bars or more the radio is basically sucking power to the radio to look for a stronger signal. therefore your battery life sucks hard core that way...

Well, I am one of the few that isn't noticing much improvement in the battery usage. I unplugged it @ 6:30 PM and didn't really mess with it. At 7:25 PM, I turned on 4G and the wi-fi tether and in about 3.5 hours it has gone from 92% to about 30% according to juiceplotter. This is 4G on, WiFi on, GPS and BT off.

So, who else is getting good battery with the 4G running? That ALWAYS drained the hell out my battery before and after the update.

I definitely have noticed an increase in battery life. Normally I would have to charge it after around 6-8 hours of solid use. Today, I took it off the charger at 2pm. It is going on 12:30am and I am at 25% after solid use. 10.5 hours so far and only 3/4 drained, after gaming, internet browsing, phone calls, youtube, and texting/emails. I hope this isn't a coincidence and the update really did help. Haven't noticed much of an improvement on wifi but that may be a discussion for another thread.

After a full charge this morning, I unplugged my phone at 7:45am, it is now 12:26am and I'm at 40% battery life. Txting throughout the day, checking a few e-mails, facebook, and web. I'd say there has been an improvement.

I updated the phone and the very next morning unplugged from the charger and went through the day with nice amount of medium usage, including heavy texting, browsing, Friendstream all day. When the phone had run out of steam It was around 14 hours later. That is a great improvement over how it ran before the update. However, day 2 after updating I unplugged the phone and within one hour of sitting on my bed it lost 25-30% from doing nothing? I just don't get it. Nothing was running except the norm and I can't put a finger on anything. The last 60% of the battery lasted well around 7-8 hours later. I noticed though, my battery indicator on top seems to show when it loses the first 10% leaving 90% on green left then it will go straight to 60-50% left without cutting off to 80/70%. Maybe the battery is bad.

So you're saying you're WiFi tethering on 4G and at 3.5 hours you have 30% left? That's really good considering reviews I've read have died at around 3.5 hours. You can't really expect great battery life since it's getting constantly drained by 4G and WiFi.

I think I'm one of few experiencing extremely terrible battery life after the update. After an hour to hour and a half of unplugging, the phone is at 70-75%, mind you I can leave the phone sitting on my desk at work, doing nothing. With moderate texting and a few minutes of web browsing, 4 hours or so later I'm left with ~25%. Also lost around 20-25% of battery after listening to or 7 songs on Pandora. After that I can pretty much watch my battery widget count down the life until it dies. I've turned off all auto updates/syncs for apps. Wifi/4G/GPS/Bluetooth are off. Followed a couple 'save battery life' threads, to no avail.

Thinking about doing a manual reset to factory settings and re-doing the OTA updates.

Suggestions?

It's weird. One day I can go 8 hours with the battery going down only to 90%.
Then the next day it goes 2 hours in and I go down to 70-80%, almost no usage sometimes.

I'm trying to figure out the cause.
It could be the battery calibration.

 

[Cowchip]

I'm still seeing the 5-10% drop right after taking it off the charger. I'll then plug it back in until it's fully charged and it seems to hold around 99% after taking it off the charger again. Strange

I found a solution to my battery life problems by turning the phone off while it is charging at night. Something is wrong with the charging circuity on this phone in that once the charging cycle is complete the phone will start to discharge even while still connected to the charger.

What makes the problem even worse is that the battery reporting and actual charge level get out of sync, and when you take the phone off the charger it shows 100% but in actuality the battery is at 50%( when leaving the Evo on while charging.)

By turning the unit off at night I am getting 16 hours of usage with Wifi, BT,GPS and exchange sync active. I would suggest to others having battery life issues give it a try for two days and see the results for yourself. I also no longer git the 10% immediate drop once the Evo is removed from the charger.

OTA updates are permanent. If you factory reset, no need to do these again, and I don't think it's even an option.

You might've read this on other forums but check the apps that do updates at intervals (Facebook, Twitter, Weather, ect. ) and set them for 1 hour or more or manual if you really don't need updates. Also I heard setting weather and clock widgets/apps to a specific location rather than "current" helps so that its not trying to use GPS to find your location.

I also no longer git the 10% immediate drop once the Evo is removed from the charger.

The reason for the quick drop is because after the phone hits 100% it stops charging and the green like will remain. So if you plug in before you go to sleep, the EVO will be done charging in an hour or two and then start running off the battery. By the time you unplug it's used 5-10% of the battery already. Try plugging immediately after the green light turns on and you'll see it'll appear to keep the first 10% longer.

I found a solution to my battery life problems by turning the phone off while it is charging at night. Something is wrong with the charging circuity on this phone in that once the charging cycle is complete the phone will start to discharge even while still connected to the charger.

The charging circuitry of the Evo appears to "disengage" after the battery reaches a full charge. From there on, it seems the phone starts draining power from the battery and none from the charger. Even if left on the charger after the light turns green, this phone doesn't seem to trickle charge like other I've used before. Even the battery icon turns from charging to full (the yellow bolt is no longer present even when the charger is still applied).

When I remove mine from the charger in the morning, it reports 100% the first couple of minutes then gradually drops to the actual remaining charge level five to ten minutes while on stand-by. By that time, the reported battery charge is usually in the low 90's.

My solution to this is to hook up the phone to the charger again after ten or fifiteen minutes and "top-off" the battery before leaving to work. Doing this, the battery meter stays at 100% for the better part of an hour then draining gradually as expected.

Using this "technique" I get much improved battery life out of my Evo, presumably by starting my day with a full charge as opposed to a partial one.

Basically said the same thing at the same time. LOL. Good tip about topping off. I do that to if I have to charge over night.

Sorry, saw your post only after posting mine, but I believe most of us have noticed this phenomenon.

 

[Husker Z]

yeah, I normally pull mine off the charger, get in the car to go to work, plug it into the charger and when it turns green again, I pull it off. That makes a HUGE difference in the first 10%.

I'm currently at hour 27 and I'm at 24% with video chatting on 4G last night and been running Pandora all morning. My battery life is no longer even worth managing after the update, it's a non factor now.

So, after two days - I surely see the battery improved for me.

Earlier - about 30-40 mins calls + an hr browsing here and there + checking mails about an hr + few camera shots + social media network, widgets, apps, etc. for an hr = My EVO would be on 10% or less after 9 hrs (all the updates are set to 1 hr check and bluetooth, gps, 4g off - WIFI on most of the time)

Now - about 30-40 mins calls + an hr browsing here and there + checking mails about an hr + few camera shots + social media network, widgets, apps, etc. for an hr = My EVO is at 60-65% after 9 hrs (all the updates are set to 1 hr check and bluetooth, gps, 4g off - WIFI on most of the time)

So, after 9 hr window - my usage is - GPS usage for 20 mins drive + an hr of extra internet browsing + few more camera shots + 30 mins extra calling + more playing around with the phone in general and my EVO at 27% with total of 14 hrs of usage (Mostly WIFI but used 4G for 15 mins and 3G for 10 mins)

Can't be more happier
