Desire battery

[Guest qwertyux]

Wrong!

If you kill processes without knowing what you do, the impact on the battery will be hard.

Let me explain:

All these task killers will kill sleeping processes ( HTC stuff, your widgets, your updates, etc..) As they sleep, they don't eat battery, and you kill them.

But unfortunately, theses processes will relaunch a few time after that you kill them, eating now a lot of battery. Then you will kill again, they will come back, etc... So you will use more battery!

These slepping processes does not arm your battery ( maybe some bad-coded)

So please stop making apology of these softwares:

I might be wrong or might be right. I don't really care about what some random guy post on a blog because I experimented with all three of them.

1. I tried with no taskiller what-so-ever.

2. I tried each one of them. One after another, one cycle of battery charge.

out of this I figured automatic task killer gives the best battery performance. Advanced Taskiller & Taskiller simply doesn't really kill everything that is running.

In Auto Taskiller, by default, it won't touch necessary sistem programs like HTC Sense & Rosie and plenty of all other stuffs.

Give it a go and figure it out yourself which one is the best for you. Only then you will now.

With the screen set to the dimmest level, bluetooth and WiFi off, sync turned off, GPS off and absolutely no browsing or music or anything like that I can admit I didn't go through a whole battery.

I went through two full batteries.

No word of a lie, on Sunday I had two fully charged batteries. The phone came off charge at 11:40am and by midnight the second battery was empty. My usage for the entire day accounts to a 2 minute phone call, two photos, two refreshes of my Gmail accoount and around 93 text messages.

Entirely unacceptable performance.

I think you have another ginky one then cause I started this thread unawares that I have services running I didn't need. From switching them off my battery is sweet for phone calls and texts alone and will last a couple of days easy.

Coming from the Hero.. I'm actually quite happy with the Desire battery..

I do charge it Daily.. Screen on Auto, 3G and Sync always On, Wifi & Bluetooth Off

I still get heavy Twitter, Facebook, Browsing, calling and text using daily with no problem.. and LOTS of G-talk usage! (4hour in all I guess)

Are you sure you guys haven't install any App that is eating your battery in the background?

Going to bed with 3G switched off.. 8 hours later I wake up with around 3% less in battery power.. SO REALLY can't complain from such a powerful mobile like the Desire.. (compared to the Hero where I wake up with 20% less on MCR 3.2- and that was the best of all ROMs I tried)

As told by others, my main 'battery drainer' is the Cell Standby.

[Guest masterpfa]

I kind of feel that Android can currently only retain charge if you don't actually use it. As soon as you do, it drops its charge like it's in freefall.

That's so true, had my Pulse on but not being used lasted for 3-4 days, as soon as I started using it, died within a few hours. All relative I guess!!

[Guest Jonnyw2k]

I can get a full days usage out of it, aload of texts, a few phone calls, auto brightness, sync on, BT on.

but on a sidenote my battery usage appears bugged:

Time Unplugged 14hours

Android system: 94%

Cell Standby: 2%

Bluetooth: 2%

Phone Idle: 2%

also the phone charges quick enough, even if you do have to plug it in for the odd hour between getting home from work and going out at night.

I'm quite a heavy user so i expect the battery to drain fast, my nexus one with 3g and internet turned off will sit quite happily in standby recieving and sending the odd text for a mater of days. But with all the features on I dont find much difference between Desire and Nexus(battery wise).

Just reading on XDA that Calendar never seems to stop running. I've killed the process and I'll see how that effects it.

Also, just realised that Flickr and Stocks were set to update, stopped both from doing so.

[Guest gregDT]

Indeed. Your experience appears to be unique. Two batteries both being faulty seems unlikely so I think it might be a fault on the phone. As suggested you should get it looked at. Bad luck ;)

Its two batteries AND two phones, ha!

[Guest RODNiC]

QUICK question.. have you tried a different charger?

Something that I had noticed on my Hero is that if I charged it from my Pc/laptop, the device would take much longer to charger, while the battery dies much quicker!

[Guest roscoe141]

I charged mine full 100% on Monday night, have been texting alot since then, made a few phonecalls, has a few plays at wifi and my battery per Power manager V1.6.2 is still 43%

You my dear sir have a gink battery or have everything running at once.

I installed Spare Parts and could see that it was very obvious that Calendar was preventing my phone from sleeping. So I opened Calendar, and went to Calendar > More ... > Calendars, and deleted all my Google Calendars and unchecked calendars 'My Calendar' and 'PC Sync'. That was about 5 hours ago and since then I've only gone down about 8%... I'm going to let the battery run dry, give it a full charge and see how long it lasts with no calendar. Then I'll try adding one calendar back in, because I do actually want to use that functionality!

But from reading through the XDA thread it seems that a lot of ppl are having a problem with the Calendar preventing their phone from sleeping, which is contributing to the fast battery drain...

[Guest jtra]

It was about £25, but no, I don't notice any real difference. Having two batteries, though, is necessary.

Third party batteries have often inflated capacity numbers. See here:

Interesting - I assume N1 / Desire batteries are the same. Above everything else, it highlights to me how I was nearly fleeced on OEM batteries!

According to this: OEM 1400mAh = $25, Seidio 1600mAh = $50

From MobileFun, I paid £25 for the Seidio, because the OEM was £30..... Now I see the OEM batteries advertised elsewhere at £15...

The very first charge will take several hours to push the battery to 90% without reaching 100% at all; use the Desire for a while draining almost all the battery charge (it won't take long, three hours at the best) and then connect it again to mains. From now on, the Desire battery will operate as expected. Tested this pretty unique behaviour on two distinct brand new devices.

The mains charge is 20% faster than the USB one.

The overall battery performance is quite good since you DON'T make hard use of Bluetooth (like listening music via A2DP).

Use the free Battery Graph app to make your tests.

[Guest Jonnyw2k]

Also, I'm on 45% after 22hours. (unplugged before full aswell) I did a full battery conditioning which means use it till it turns itself off, then plug it into charge leaving it turned off and leave it on charge until its full + 6hours(so best todo it overnight) and I must say the battery life is amazing :huh:

Update: Even with all my google calendars unchecked the Calendar is still the biggest user of battery charge over the last few days ... seems to be a bit better if I manually kill the 'Connectivity Service'. Still pretty crap though, I'm getting 30-40 hours with normal use ie. browsing, checking emails, watching some youtube vids, a few calls and 10-20 SMS...

[Guest Rdy2Go]

I've got no issues with the callendar app, moderate use (mail sync every hour, some sms, voice calls) and I have to charge it TWICE A DAY.

Its battery life is approximately six time or eight times shorter than my previous smartphone (Omnia II).

6-8 hours vs. 48 hours!!!

I think it's mainly because of keeping 3G connection on, with Windows Mobile there was a timeout (2 minutes) when the connection was automatically closed thus saving lots of battery life.

Do you know any app for Android that can do exactly the same: disconnect 3G when idle, connect 3G automatically when application wants to connect to the internet.

[Guest fatboygrim]

6-8 hours vs. 48 hours!!!

if your htc desire is seriously only lasting 6-8 hours, then you need to take it back and get it replaced - mine easily lasts 48 hours, and that's with 3G, email, lots of applications etc all running

3G on all the time, email sync 1/hour (exchange, including callendar), nothing else is synced. 3G reception is excellent (max signal)

2 hours with screen on (25% of the time).

What are your settings?

[Guest The_IMF]

Using Generic ROM

Unplugged from charger 3 hours ago.

Battery Widget tells me that my battery is down to 97%.

3G is on but internet always on is not enabled.

Everything synching fine every 1 hour.

My Calendar uses 0% when I check battery stats. I have deselected this from synching anyway as I don't use the calendar on a daily basis.

Not using any task killer app at all, all my memory is already full of apps so not like I have nothing installed on there.

Widgets that I use which are updating fine:

Stocks, Friendstream, Music, Engadget News, HTC Clock/Weather.

My Desire lasts a full day on a single charge which I think is very impressive for what I have running (7am - 11pm).

Show me a high end smartphone that doesn't need charging every night that has the same features as the Desire? Every smartphone I've had over the last eight years (a good 14 of them!) has needed to be charged every night with one exception, the Palm Treo Pro which would last just under two days.

I think its also key to point out that during my first week of owning the Desire the battery was only lasting 3/4's of a day, then suddenly after about a week or so usage and without any real reason it improved drastically. Now at the end of the day I usually get the 15% warning just before I put it on charge before I sleep.

Thanks

I just disabled "Always on" as no one seems to know what it really means except it is reported to draing battery fast,

my Desire is just one week old, maybe I'm going to see some improvements in the following days.

One day would be just fine with normal, smartphone use, I don't want to get rid of the features and use it as dumb phone :huh:)

[Guest Sashimi]

Last sunday, my desire had no battery after 6h of pretty moderate use (1h of music, 10min of 3G web surfing, 5min phone call).

I'm not satisfied with the battery duration :/

I've got a question : why the hell is there bluetooth related stuff running even when the bluetooth radio is off ?!!

[Guest Superangel]

Hi guys

I don't use a lot of data, so with the following settings, I get around 3-4 days usage before charging:

• 3G/Mobile Data off, GSM network selected
  
• Wifi off
  
• Bluetooth off
  
• Auto-sync off
  
• GPS off
  
• Screen brightness automatic
  
• EStrongs to manually kill processes
  

Whenever I need data, I just use the 'Power Widget' to quickly enable wifi, or 'Quick Settings' (excellent app) to toggle 3G. When I'm done, I switch them off, as it only takes a second or two.

I still use my phone to play games, download apps, check my email and social networks etc., but granted I don't take a lot of calls or have it on all day.

On the few occasions where I hammer it downloading things and playing games a lot, I tend to get around a day's heavy usage.
