Using auto, I'm getting 80 km / 1500 m elevation out of the battery. Pretty decent!

Hi, I'm curious, are you saying that just by use auto you're able to ride this mileage and attitude? Nothing else ? How this mode manage battery and power?

I have been doing longer XC rides lately using tyres with less rolling resistance. Maxxis Forekaster front, Ardent rear. The Forekaster is totally fine also for lighter trail use, but I'm swapping out the Ardent, it lacks grip. I'm not sure how much these tyres impact range vs the standard Butchers, maybe 5-7%? Main reason for trying something else was that (especially) the front Butcher throws a lot of gravel which is annoying. Also they feel a bit sluggish when doing longer rides.

About the auto mode, I don't think there's anything special about it, you can probably use dynamic microtune to the same effect. The motor has an inclination sensor which enables you to stay in the same mode almost all the time.

Which auto mode is that and have you tried all 3 and found any significant changes in range?

Regular auto. I tried auto-, the main difference seems to be that you get less assistance when going uphill. On the flat they're pretty much the same, both giving too much assistance IMO. If Specialized could tune this down a bit there's additional range to be had. I believe there's another member here that has the same view.
 
Have you tried to use the screen with assistlevel?
In auto easy and power moves even as you pedal, in dynamic microtune they don't.
Mayby you can play around with them to find a sweetspot.
With all the possibilities to adjust the motor I'm sure in one way or another it should be a way to find a sweetspot for everyone but it will take some time to find it and get used to it.
I didn't like full overrun at the beginning found it scary but by being more aware and used to it since it changes the whole ride experience after a while I quite like it.
 
I participated in a 3-day competition this weekend. On the last two days, I had to conserve the battery and ended each day with 11%. After the race, the bike was left in a closed park for about 2 hours for a possible check. The strange thing is that when I picked it up, the battery was down to just 3-4%. Is this normal?

I have noticed when I leave the bike at the evening and pick it up in the morning battery is always down 3-4% no matter how full it was and I doubt "Find My" draw that much battery
Never happened with G3.

I’ve noticed a very similar effect on my bike as well. Especially after longer rides, when I finish with something like 30–40% (or even less) left, the next day the display almost always shows a few percent lower – usually in the range of 4–5% less than when I parked it.
Interestingly, this doesn’t happen when I charge the battery up to higher levels. For example, if I leave it at 80%, 90% or even 100%, the charge level is usually still exactly the same the next day.

My guess is that this only happens after actual use of the bike. At some point later, maybe during the night while it’s just standing still, the system seems to “wake up” again for a short moment – either to recharge the display’s internal battery or because the battery management system is doing some correction. That could explain why a few extra percent are lost in those cases.
The bike’s manual even mentions that the system sometimes recharges the display’s internal battery by itself and wakes up from deep sleep to do so. Maybe that’s exactly the effect we’re seeing here – but I’m not entirely sure.

I also tried to disable the Find My function as much as possible, even uninstalled the app on my smartphone and deactivated the bike feature in the settings, just to verify if that might be the reason for the small drain. But it didn’t seem to make any difference – so I don’t think that’s the cause.
 
My guess is that it is temperature related, battery cools down after use.
 
Back to topic:

Here’s a summary of my real-world battery usage and range from the last ride:

Rider & Bike Setup:
  • Rider weight (incl. gear): approx. 90 kg (198 lbs)
  • Bike: Levo 4 Pro, size S4
  • Tires: Schwalbe Radial (quite draggy)
  • Total bike weight: approx. 24.5 kg (54 lbs)
  • Battery: standard 840Wh
Ride Log:
  • Distance: 47 km (29.2 miles)
  • Elevation gain: 1,627 m (5,337 ft)
  • Mode usage: 39% Auto / 31% Trail / 28% Turbo
  • Battery used: 99% (1% remaining – motor still delivered full power)
  • Adjusted pedaling power: 147W
  • Adjusted ride time: 2h 38m
Motor Settings:
  • Shuttle: Low (except last climb)
  • Responsiveness: Medium
  • Overrun: Default
  • Auto Mode: - (minus)
  • Trail Mode: 25/85
  • Turbo Mode: 75/100
  • Eco Mode: 10/30
Note: On the final climb, I switched to "Shuttle: High" to intentionally drain the battery and test whether the motor would reduce power below 10% battery. It didn’t – full support was still available.

Conclusion:

Overall, I’m very satisfied. I didn’t need to conserve battery, rode plenty of trails in a short time, and still got a solid workout. Given the total weight and performance, the Levo 4 delivered exactly what I expected when I made the purchase. Longer rides are definitely possible with lower support settings, but that wasn’t my goal this time.

Hope this helps!

Here's what I understood.

The cause is the recalibration of the battery cells.

Recalibration consists (as far as I know) in discharging the cells with a higher voltage to bring all cells to the level of the one with the lowest voltage; in this way a subsequent recharge may bring all the cells to the maximum voltage.
This because, to preserve the cells, the charge is interrupted when a cell has reached the maximum permitted voltage and therefore the charge is interrupted for all the cells, even for those that would require a further charge.

It seems to me that in previous models as TL G3 the recalibration process took place in the final charging phase, in fact it took a long time to finish.
Instead in G4 the charging process ends as soon as it reaches 100% .
This is possible because the recalibration has already been done.

Regarding this topic you can find this in User Manual:

13.16.3 STATE OF CHARGE AT START UP
When turning on the bicycle, the SOC shown on the display or in the app may differ from the value displayed before powering the bicycle off. This may be caused by battery recalibration when the bicycle is powered off.

The manual does not say how long after the turn off of the bike the recalibration process takes place;
I noticed that it never happened in stops during a ride

I haven't seen this, but I always take the battery out and leave it in a partial discharged state, and plug it in the night before I'm gonna use it. I figure treating the battery like a princess can only be good in the long run.
 
I recently did wine 2 whales race on my S4 levo. I weigh around 105kg fully kitted. The race has 3 staged days, each day has around 65km and 1250m of climbing. There are 3 water points and the 2nd being the only point one could change the battery on the bike if you so wished. The race is done with a partner.

On the first day we left our settings pretty stock. We tried to manage the battery as best we could as the water point was 45km and 700m of climbing away. Most of the 1st day was done in trail with some turbo boosts up punchy climbs.

I ran out of battery on the last climb to the battery change water point about 43km into the ride and around 500m of climbing. Last 2km was hell to say the least. So we almost made it being forced to use about 90% trail for most of the ride.

2nd day was pretty much the same amount of km and climbing to the battery change point. However after the 1st day we decided to change trail onto 25/80. That made a massive difference. This reminded me of my SL days and getting the most out of the small battery. Common sense would tell you the harder you work the better the battery life.

so for the guys wanting longer ride, just turn the power up a notch or two and turn the ease ALL the way down. This will force you to keep spinning and get your there. I found it to be quite enjoyable this way instead of being pulled along all the time.

Did you do a battery swap on day 2?

I managed to get through each day on one 700 battery, but riding 20/50 exclusively (gen 2 as I felt the 29er wheel on the back was more efficient.)
