Battery problem - R2

I think my battery has some problem. When it is fully charged, I get only about 3 hours of charge. It is happening since some days to today. Before this problem I was getting 5:30 - 6 hrs. But my battery was showing variable levels of charge anyway, going from 4hrs to 6hrs.

Is someone having this problem too? What could it be? Could it be because of Throttle Stop? Is my battery with a great problem? Thank you all that will help me.

OBS: I looked other threads and did not found any advice or solution. So I'm asking here for anyone that can help me with this.

 

Your battery would likely be more consistent if you used throttlestop, less time but more consistent. I would contact dell about a replacement.

 

Yea I'm thinking about it...it suxx a lot since I live in Brazil and a replacement here shall take forever to be done, because the battery probably will come from USA. Thanks anyway.

Anyone who have another solution, a tip to fix it, please tell me too. I'm really disappointed with this battery's quality...and sad. =/

 

Not everything comes out perfect =/ Just wish there was better quality control.

 

I recommend installing BatteryBar and check if it reports high battery wear (which would be grounds for a replacement), or if you're running at a high discharge rate.

 

Use battery bar, also not meaning to 'thread hi-jack' but how is Dell on replacing chargers? Mine has a connection issue at the base where it connects to an outlet, I have to shake and bend the wire to get power flowing. I would call but I've been doing a little drinking lol.

 

Unfortunately...should be this way.

I already used Battery Bar =/. Same charge report.

Nah, you can use the thread for battery issues on you way =]. Your problem can be a broken cable. Maybe you should call Dell for a replacement. Need to have caution when bending cables, because sometimes they break easily.

 

Ok, but I was interested in what Battery Bar is reporting in the lines "Discharge Rate" (while unplugged) and "Battery Wear," not just the estimated charge time. If you can give those numbers, it might be helpful.

 

Oh ok, let me post it here:

Percentage charged: 78,9%
Capacity: 49.700 mWh from 62.720 mWh
Discharge Rate: -24.376 mWh
Battery Wear: 0,0% from 43.600 mWh

BatteryBar version 3.4.4

Thank you cappielloa and all of you which are supporting.

 

You have a small mwh than me, I have about 64,000 but that may be because you are onlyt at 79% and I'm at 100%
Your discharge rate is too high, what are you running I have 8 tabes in firefox opened, steam, downloading LOTRO and have throttle stop running and mine is 23k. When I turn off TS I have it at 19k screen max brightness. And my video card was overclocked.

 

Here is the great problem: I'm running only this page. This %$*& battery has a problem, I'm starting to get in reality...I will tell Dell that I can't stay without my notebook so that they send me another battery and then I send this one to them.

 

Problem is though I don't think that will decrease the useage of the mwh something else is going on there. What brightness setting are you using? Throttlestop or any other OC going on? What processes do you have and what % of the CPU is being used in task manager? Was the battery actually reporting fully charged when you gave us those settings or was it really at 79%?

 

I don't think it's the battery, I think you have background programs running that are cutting into your battery life. My discharge rate on battery runs around 14,000-15,000 mWh (no TS, low screen brightness). To echo the post above me, what is your CPU usage at?

 

Ok I will report this things when I get full battery charge.

 

The discharge rate is the problem. A reasonably well-tweaked M11x R2 should get around 12,000mWh - 15,000mWh.

You have some background processes that are draining the battery pretty quickly. Can you figure out what it is? Try turning off ThrottleStop (which should definitely be OFF when you're running on battery), other startup programs, AlienFX lighting, and screen brightness. Also make sure that your Windows Power Options settings is Balanced (and not High Performance).

 

Ok dudes, here is the report:

Battery Charge: 100%
Discharge Rate: -22.942 mWh
Battery Wear: 2,8% from 64.530 mWh
Max Capacity: 62.720 mWh

Windows Power Options: Balanced

CPU Usage: 24-40%

Only running Online Antivirus Scan and this page (maybe some virus infected my note and is causing this...IMO). No ThrottleStop activated. CPU OC'd to 164 Mhz. No OC on GPU.

Thanks.

 

Open task manager and go to the processes tab. Try to find which process(es) are using a notable CPU %. I idle with under 5% CPU usage.

 

The problem is your cpu usage. 24%-40% is way too high. It should be closer to 0%-5%. Use task manager to find what is causing the high cpu usage, and you will know why your battery life sucks

 

Now my CPU usage is around 10-13%, but my battery discharge rate and battery charge time still is at the same behaviour. Can it be due the graphic driver? I'm using Nvidia 260.99.

 

Check your task manager. You can view by which programs are using CPU. Turn the brightness down on the screen to about half and turn off the lighting on the keyboard and see what you get, make sure AV is off as well. And try putting it on Power saver.

 

I checked it Ninja, but now my CPU is using up to only 6% of its capacity and I still get only about 3 hrs of battery duration. I tryied a lot of things and nothing worked to fix it. I'm getting - 18.500/-19.500 mW of discharge rate now, a little less than before, but its still a great value.

 

It's not your battery that something is wrong it is still those tasks running.

 

Its weird. There be a way to find what is causing this...

 

Worst case scenario, a Windows reinstall may be around the corner.

 

Hey dudes, I'm back. The windows reinstall isn't just around the corner, its already in my house's door. Today a Dell's technician came in my house to change the battery for a new one (I requested my warrant). But, guess what: the problem persisted! Well, I don't have other alternative unless to do a Windows reinstall...=/

Thank you all for your help! You guys were right: that wasn't a battery problem.
