If you want a laptop purely based on Battery Life, Dell isn't the option, that would be the M1 MacBook Air. Yeah yeah apple and macos but that battery life is unbelievable.

Generally, if you want longer battery life, you want the biggest battery paired with the lowest powered components. I'd avoid using the H class intel processors as they chug power and by the sounds of it, you won't need a dedicated GPU, which would also use more power.

Dell Latitude would probs be worth looking at especially if you go for a 66Whr battery.

>Preferable screen sizes between 13 and 14 inches.

XPS 13 it is, then. Mine sometimes runs a bit hot but battery life is strong.

My XPS 9570 can get me through a day without a problem, but it is the model with a 97Whr battery, and that is using programs that don’t need the NVIDIA GPU. Also, to get a bit more out of the battery, I went with the Full-HD panel, and I went with the i7 (the i5 didn’t have quite enough power for my needs, and the i9 was too powerful). My typical applications are writing environments, a bit of coding and PowerPoint, so not very challenging applications. The battery often displays 8 or 9 hours of battery life, and it gets me through a day of lectures just fine.

All arm based processors have great battery life. So m3 or xelite chips

go with lenovo loq rtx 4050 with ryzen 7 7840hs , it gives great backup - https://www.flipkart.com/lenovo-loq-ai-powered-amd-ryzen-7-octa-core-7840hs-16-gb-512-gb-ssd-windows-11-home-6-graphics-nvidia-geforce-rtx-4050-15aph8-gaming-laptop/p/itm21f19c8b9bf94?pid=COMGRC9RBJNHXXKY&lid=LSTCOMGRC9RBJNHXXKYZHLCDZ&marketplace=FLIPKART&q=loq+7840hs&store=search.flipkart.com&srno=s_1_1&otracker=search&otracker1=search&fm=Search&iid=75d13b61-dfe6-4b71-a3e8-11011cb857d0.COMGRC9RBJNHXXKY.SEARCH&ppt=sp&ppn=sp&ssid=hy51xp5my80000001720828537447&qH=289d56288e0a13f6

Get a non gaming laptop with a dedicated GPU (generally a 50 class GPU). They'll do the job.

Great Deals!

don't buy dell, there is camera laggying issues with zoom meeting, you can search here and find a lot people mentioned it

I have the Dell XPS 16 refurb NOTHING BUT PROBLEMS and can't get help. HDMI Sound not working - Touch Screen not working - the f1 to f12 keys are lit up rather than the small volume, etc pics - can't get the bluetooth mouse to connect. The Premium Support is terrible.

I would take the advice of others:

Lenovo ThinkPad P-Series

HP Zenbook

Lenovo Ideapad

whatever you do, don't order directly from dell. you'll never get it and they wont give your money back.

really really really depends on your needs and budget

My favorite travel laptop is the Asus Expertbook B9450 with a weak 10th generation processor (i5 or i7). It's a little over two pounds and has great battery life. They are fairly cheap used; too expensive if you find a new one.

Could looking laptop with Intel Lunar Lake processor.

MacBook Air

I’m selling my brand NEW Dell Inspiron 15 because my son wants an M4 Air, so it’s time for this one to go! It’s a great laptop for students, professionals, or anyone looking for powerful performance on a budget. Bought it on jan 22nd 2025

Specs: 13th Gen Intel® Core™ i7 (10 cores, up to 5.0 GHz Turbo) 15.6” Touchscreen Display – FHD, IPS, Anti-Glare 16GB RAM & 1TB SSD – Super fast and spacious Battery Life – Up to 9 hours, 15 minutes Sleek Aluminum Shell – Platinum Silver finish Price: $549.99

I have created a comprehensive guide to help people figure out what specs to look for when buying a modern laptop. It's a 10-20 minute read. GL M8.

I have liked some of the IdeaPads with the Ryzen 7 processor. I got one called an IdeaPad 1 with Ryzen 7 5700 and 12 gb memory from Best Buy USA. Easy to get 6.5 hours. Ryzen 7 is fast, energy efficient, minimal heat.

I saw something similar called an IdeaPad 5 Ryzen 7 5800 on Lenovo site.

Another good one to think about an Acer Swift 3. I saw a review in a laptop blog/magazine. They said that the 12 hours claimed by Acer was a little hopeful, but they did get a legit 9.5 hours.

Edited

There are lots of laptops that last 6 hours...please fill out the form to narrow the search https://www.reddit.com/r/SuggestALaptop/wiki/form/

Also how bright is max brightness? Some laptops have really nice screens that get very bright but would kill the battery if you left it on max all the time. But then there are others with really bad screens that are super dim and they would technically be at max brightness and last longer simple bc max brightness isn't very bright.

Lenovo T16 G1

Dell Latitude 9520

For the best battery life for office you're looking at Snapdragon X, or x elite or Intel Lunar Lake.

If you never play games then snapdragon x or x elite wins.

If you play games then you have to go intel.

You also have to set the power profiles to use less power on intel.

Snapdragon lasts way longer for what you're doing though. Probably 2x what intel will give you.

Snapdragon is an Arm processor and there are a lot of programs that don't work on it. Make sure to Google check if what you use is compatible with arm windows.

Z13 Thinkpad is right there with the macbooks IMO. The one I had would go a full day and then some before throttling for battery level.

if you like macOs, just get a macbook air

for windows, the surface laptop 7 with snappdragon is really good

if you want cheap, used M1 MacBook Air (ideally with 16gb ram, okay if not).

if you want to pay a bit more, get the new MacBook Air that just came out.

For storage, just get an external drive of some kind for the media stuff. If you can find a laptop with an upgradable NVMe, you can do that, but good luck in this market to get one while still having a decent battery life

The Ryzen 7u have good battery life

Thinkpad T14 with Ryzen 7 7730 would work.

The new snapdragon cpus like Swift 14 AI seem to get a legitimate 12 to 14 hours and work well with office 365 and Ms copilot. These are new in last 12 months

Those “new” Dell batteries were possibly fabricated months ago and sat in a warehouse unused until your machine was ordered and it was put together.

The battery on my xps 9570 reached it’s “end of life” after 4 months of ownership.

FYI, my Latitude e5450 had a 3 years old battery. AIDA64 reported a 65% capacity, and meanwhile, Dell BIOS still said excelent lmao, even tho it had started bulging lol.

Ich würde mich der Frage des Users anschließen. Mein Latitude 5310 ist jetzt fast 5 Jahre alt. Seit drei Wochen habe ich das Problem, dass er sich solange er nicht am Stromkabel hängt sehr schnell entlädt. Bis zum vergangenen Jahr hielt er locker zwei Tage von 8 - 16 Uhr Vorlesungen ohne laden durch. Nach einem Update auf Windows 11 reduzierte sich dies auf die Hälfte. Seit drei Wochen ist nach einer Stunde Laufzeit Schluss. Wie sehe ich genau, welche Leistung der Akku noch hat? - Ich würde ihn bei schwacher Leistung dann austauschen lassen.

I had two batteries form my E7470s last a little over two years.

It really depends on the number of cells and how they're arranged. A single cell device, typically a smartphone or tablet, will generally last a very long time if taken care of because it doesn't have to balance against other cells. A 4 cell battery that is 2 in series in 2 in parallel I would like to expect to last longer than a battery that is 4 cells in series. The runtime has to rely on the weakest cell.

The Latitude 5420 only offers 3 cell and 4 cell batteries in series. I would say the lifespan should be similar but if one cell fails before the others it will be more noticeable on the 4 cell battery. Generally a drop from 40% to 5% means that one cell is wearing out before the others and/or the battery is not properly calibrated. Generally the 5% is voltage specific, a high draw reaching that voltage will engage a shutdown to prevent data loss.

Is the battery in the laptop Dell original? I have seen aftermarket batteries ignore the threshold settings.

Depends on how it was used or abused. Your due for a new 1 though (5-6yr old).

6 years is a good lifespan for a battery. Even unused on the shelf, they're good for 3-5 years.

Unfortunately the tools to show health and capacity are based on observations and calculations. If you run it through several charge and discharge cycles you'll see the listed capacity fall dramatically and fairly soon it won't charge at all and BIOS/dell utility will report it needs to be replaced.

Luckily batteries for older laptops are usually pretty cheap on ebay. They are new old stock so they won't be perfect but I just replaced a 62WH one in my latitude for $22 and it shows 96.5% charge capacity and lasts several hours or normal use.

When you say it doesn't respect the 80%, are you sure you didn't set it to 80% start and not stop? I.e start charging at 80% and stop when full. The upper limit is a less common setting. Mine is set in BIOS to start at 95 and stop at 100 (just to eliminate unnecessary brief charge cycles when it was only unplugged for a couple minutes or has a bit of normal discharge) and lasted around 8 years. It is a secondary laptop but still works quite well so was worth the $20 bucks.
