How did you manage the battery before?

can also edit power plan to limit them to like 50% of their base clock, around 1 GHz. Someone mentioned setting a very low power limit with some program - not sure if this is just equivalent to limiting the clock speed though.

All the manufacturers battery life predictions are based on optimal conditions. It could be that where you’re using It is very hot or very humid or there are some other environmental factor that is degrading battery performance. This is an industry situation that wouldn’t really be resolved by going with another manufacturer

Basically, if you cut the projected battery life in half for a new battery and then in half again after a year, that’s going to be fairly accurate. Again, this is not Dell, this is the whole industry.

That's an 11th gen processor laptop, is the battery new or still the one from 2020?

Even when new the 11th gen processor was power hungry.

Most laptop / notebook batteries are only rated for about 500 cycles, FWIW. After that, they lose about half capacity.

you can check how much the battery has worn out. But I have used 5420 before, with a 41Wh battery, it lasts around 4-5 hours for web browsing with a new battery.

Without knowing the exact CPU, I have a Latitude with an i5-1145G7, which is on the CPU list for the 5420, that is rated for 25 hours with roughly 106Whr worth of batteries.  That is also including it is set to cTDP up on the firmware which is not present on the 5420.

The thing to consider, ignoring the possibility the computer boosts on battery power, is that under normal use a 18 watt CPU with a 41Whr battery is only going to get 2 hours when Wi-Fi, RAM, LCD and SSD power consumption is accounted for at moderate utilization.  To get 8 hours, or rather 5 when scaling down, would mean the CPU may need to be underclocked as well a battery efficient SSD (as Windows accesses them often).

Most computers that I have that get the rated battery life idle at 1.6 watts while connected to a network, though I can get close to 1.1 watts with all wireless off and the screen backlight set to minimum.

A 5-digit H series is a performance processor and may be drawing around 50 watts, whereas a i7 U series only draws 15 watts.

Combined with a video card, you will struggle to get a long battery life. There is a 97 watt hour battery available for precisions that may give you more life (unless you already have it)

Generally speaking processors have different power states.  You can reduce this power at the cost of performance.

While some Dell Precisions can get decent battery life the consumption is going to be higher than an Ultrabook.  I would need to know the model number to glean into the numbers you have mentioned.

did you figure this thing out, i have a precision 5680 as well with that same setup expect 16gb ram and a 1080p oled, my battery sometimes drains like crazy

for best and longest battery life and health:reduce heavily the performance of your laptop by using a powersave mode from your bios,set up a charging threashold lower than the full 100% capacity and use like 50% as a start for charging,always use battery save mode when on battery,reduce the screen brightness,you can set in windows different settings when your laptop isn't plugged in and if you have a graphics card make windows use the igpu in the most used apps instead.

If you have the laptop plugged in constantly disconnect the battery. Charge it occasionally

This is some very interesting recommendations which come at a good time for me since I'm having battery issues with the kind of bizarre XPS 16 (refurbished) which Dell sent me in replacement for my beloved but faulty XPS 15. But I have a question for you: I'm aware of the Killer interface for network but had not realized it was something that I could separate from network operations as a whole. Do you know what it actually does? Besides bothering me about things it says I ought to do like buy a new router? So it has nothing to do with the operation of tcpip and so on?

wow. sounds good. that report has a ton of daily detail, which i assume is not generally useful. basically, we want to compare "design capacity" (intended), vs "full charge" (what we're getting now).

we want to look at the last line in the report?

Since OS install

At Full Charge

At Design Capacity

|Active|Connected Standby| |---|---| |5:40:13|31:51:27| ||50 % / 16 h|

So what do i have left? i'm running at 50% of theoretical capacity? and 83% of what capacity?

I owned a Dell XPS 9500 4k since 2020. It's still my daily driver. I upgraded the ram to 64gb and second SD slot 512 gb . I recently repasted the CPU and GPU , honestly it was super easy. Just followed along a youtube video. I use Throttlestop 9.2 I set the Multiplier at 20 , Disable Turbo, BD Prochot checked, Speedsep checked and C1E checked. My CPU and GPU Idles between 39 - 50 Celcius. I still can game on this laptop. Battery life is at 21% still gives me 2 hours of battery life just watching shows. I just ordered a battery for 40 bucks on ebay. I think this laptop will continue to hold up for a long time. Maybe an other five years to be honest with you.

Thermal paste on what? The battery?
Also, I recommend opening it up and dusting and cleaning it out once a year.

Or you could just buy a MacBook and not have to worry about it. After 3 years I finally made the switch and now my life is fire

the only downfall of the 7373. I'm hoping there is a battery that has larger (even if just slightly) capacity that we can swap in. I know the ryzen version is slightly bigger.

How old is the laptop? Can you find a reading for how much battery capacity remains? After two or three years it can drop quite a bit.

In the mean time you could look into undervolting, look at what background processes are running? (Do you have MS AV as well as a third party AV installed and running?) Reducing screen brightness will also help.

Does this laptop have an HDD or SSD? Swapping an SSD for the HDD will give you a nice performance boost as well as reducing battery usage.

You could reduce the clock of the cpu

"Gaming" laptops typically don't have good battery life. You can change your power plan to the more conservative option, turn down brightness, etc.

1. Lower screen brightness.

2. Limit CPU/GPU max % usage in power settings.

3. Turn off applications as many as possible like if you have bunch of monitoring softwares etc.

Turn it off

Plug it in

I use mine on battery until it drains and then charge. Or mostly use it charged. The only way I've seen to boost battery life is replacing the battery.

I've heard the same, but not seen any real solid facts to back it up. If that were the case, just unplugging it while you're using it, and letting it discharge is an option. Or, leave it uplugged over night.

That being said, the most critical thing to avoid is completely discharging the battery. I try not to let them get below 20%. If you drain the battery completely, it looses it's ability to hold as much of a charge little by little, each time it happens.

Use Dell Power Manager and set a charging limit. Set the limit to around 40% since you primarily use it on AC. With this setting, it won't charge more than the specified amount.
